Plugging Holes In The GPL 105
For the last several weeks I've been thinking about the word "distribution" because the meaning of that word and the way we interpret are going to be one of the most important debates for the free software movement in the next several years. The problem is that a loose definition of the word opens up many loopholes in the GNU General Public License, both for corporations and average Internet users.
The word is crucial because it lies at the core of one of the most distinctive requirements of one of the most distinctive open source licenses. If you modify software protected by the GNU General Public License and then distribute the new version, you must also distribute the source code.
On the face of it, this requirement sounds pretty easy to satisfy. Every time you give someone a copy of the binary version of the code, you give them a copy of the source code. The two should travel together or at least in close proximity.
The main reason the clause is part of the GNU GPL is because Richard Stallman, the license's principal author, believes that anyone who drinks from the commonweal should give back. If you benefit from the sharing of others, then you should make sure to give something back.
But, if you dig a bit deeper, the notion of distribution becomes a convoluted. Some of the ways that people share software with each other may not really count as distributions.
The distribution requirement is one of the concessions that Stallman made to the users and their sanity. You don't need to share all of the changes you make to the code -- only the code you distribute. Sharing everything might unleash a painful process, one that would push too much untested code on the world. Do we really want everyone sharing their files everytime they save a copy to do a new compile? The compromise, which sounds reasonable, only requires you to share the source code when you share the software.
The problem is that the act of giving someone a copy is getting a bit harder to define, because of the new features embedded in operating systems, the near omnipresence of the Internet, and the new interest by corporations in the phenomenon of open source software. Many of these new wrinkles are confusing because they push the boundaries of both technology and license.
The biggest problem is that new features are making it easier and easier for two programs to work in synchrony without being formally linked together. You might use one piece of GPL protected software to edit files and one proprietary program to process them. The GPL embraces these sorts of bright lines between programs; mixing closed source programs with open source ones is not forbidden.
However, it's easy now for people to write scripts that link seemingly disparate programs -- thousands of them, even -- and then execute them in concert. I know one company that uses Adobe Photoshop to process images created by a proprietary, in-house tool. Is the software linked together? The process is entirely automated and works with no human intervention once initiated.
The line blurs elsewhere, too. On some cool multiprocessor machines, two supposedly separate and independent programs can execute on different processors and send messages back and forth. Where do we draw the line?
The process is getting even more confusing when the Web gets involved. Imagine one programmer who creates a tight weather prediction package for the Web that stores the forecast in a GPL-protected database. The programmer links all of the proprietary code together with the database. The result is a new package that extends the database and thus must be shared completely with the world according to the GPL. This is certainly fair. If anything, the GPL-protected database code is doing the bulk of the work. The programmer succeeded by standing on the shoulders of giants.
Now, consider a different programmer who, for the sake of example, stores the database of forecasting information on one Web server in California. The main website which dispenses the data to the world sits in NYC on the other end of a fast backbone. The main Web site uses the proprietary code to look up data in California before publishing it on the Web.
Should this programmer be forced to share the NYC code with the world? Let's say the programmer starts selling the package as a $10,000 proprietary package for adding cool weather graphics to a Web site. Anyone who buys it must install the GPL-protected database and make sure that it's always running. But are the two programs technically linked together? The California server might be GPL-protected, but does this extend to NYC? The NYC site certainly can't operate without the California server, right? What would happen if the server was right next door? What if it was running on the same machine under a different user's login?
Stallman anticipated this problem and offered a Lesser version of the GPL which would let people link with GPL-protected libraries without releasing the software to the larger program. But that lesser version, known by the acronym LGPL, is a bit rare.
I don't envy the people who try to make sensible decisions about what counts as a distribution and what doesn't. Stallman has done as good a job as he possibly can. He sensibly recognized that GPL-protected code was going to have to live in close proximity to non-GPL code. He realized that these programs might be linked together by shell scripts and other tools. But where do you draw the line?
The problem is being stretched as the world of corporate computing discovers open source software. In the past, the definition of "distribution" was easy because everyone was just an individual hacker. If you gave a program to your buddy, you distributed it.
But imagine that MegaSoft decides that it really needs an internal editing system for filling out proprietary MegaSoft paperwork. The programmers love Emacs so they take GNU Emacs and add a few tweaks for providing the user with forms. Some of it is written in Emacs LISP and some of it requires a few neat extensions to the basic Emacs module. Everyone loves the software and they start shipping it to all of the PCs in the corporations.
Is this a distribution? Some might argue that it isn't. A corporation is just a legal fiction for a single person. It's not much different than Bob the hacker writing the code for his own use. Bob doesn't need to share the source code until Bob starts giving it to Alice, the other hacker. By this argument, MegaSoft doesn't need to share the source unless MegaSoft ships the software to another company or non-employee. Even if there are 100,000 employees in MegaSoft, there hasn't been a distribution.
There are millions of problems with thinking of a corporation as a single hacker. What if the corporation splits in three like AT&T? Do all three get the code? Should only one? What if the corporation is aquired by SuperMegaSoft? Is this a distribution? What if the form-enabled Emacs was the only reason that MegaSoft was worth anything because the rest of MegaSoft wasted the rest of their VC money on a plan to sell clothing advice to fashion victims? (www.DrBoo.com)
But there are other problems with forcing corporations to share all of the code all of the time. Are corporate teams that much different than free software teams? Shouldn't they have the freedom to work for several months without distributing the changes? It saves us from buggy pre-alpha code and it saves them from repetitive bug reports. ("It crashes when I start it.") Where do we draw the line? Why can't they enjoy the same freedom as individual hackers to make a few, krufty changes to the source code and leave it at that?
There are deeper problems in corporations. By many measures, Tivo is a good example of the power of free software. The digital video recorder for television signals runs on top of the Linux kernel. The only reason anyone knows this is because Tivo gives Linux credit and it shares copies of the changes it made to the Linux kernel. In many ways, it's a model of a great corporate citizen in the world of free software.
But Tivo didn't share the source code to their television recording front end. It's a separate program running on the machine. No one's gotten in trouble for running proprietary code on top of a GPL-protected kernel.
The Tivo, though, is different. It starts up the proprietary code when it boots and the user has no way to communicate directly with the kernel. The user can't use any of the standard UNIX commands to control the machine. The user can't do anything that the proprietary front end doesn't allow. This will probably save millions of users the grief of reformatting their hard drive.
But is this really fair? If the user can't pry apart the Tivo front end from the Linux kernel, are the programs intertwined enough to become the same program? If so, shouldn't Tivo be releasing the source code to the front end as well?
There are deeper problems on the horizon. Some companies are now "loaning" or "renting" software. In some cases, you don't even keep copies on your local machine. You just download it from the server and use it for a bit.
Is this a distribution? On one hand, the user doesn't get to keep anything. On the other hand, who do we think they're fooling? The whole system is just ephemeral clouds of bits flying around. To think that anyone "owns" something as abstract as software is like saying that someone "owns" a cat.
In fact, we can take this one step further. What is the real difference between using the software on their server and downloading it? Is there much difference between using the Hotmail web-based email system or running Eudora on your desktop? There isn't much difference to the user, even though there are big legal differences. In one case, Hotmail still owns the software and it's all proprietary. In the other, Eudora sold you a copy. Well, maybe they sold you a license. Well, who really knows?
I won't try to find answers for any of the questions about distributions. This is, in some respects, a chicken's response. There are millions of ways to find things wrong with the world. A real leader would find solutions. But it's also important for these answers to come from the community at large. There should be a long debate that focuses on the needs of the users and the creators of free software.
The biggest problem is that the answers are more political than technical. It's easy to define what an piece of software should do if it, say, encounters a request to divide by zero. It's much harder to handle definitions of what is and is not a distribution.
The community needs to weigh two different features of free software: On one hand, there's the fun of taking apart the source code and fixing it. On the other is the responsiblity for contributing back to the common code base. Stallman chose to tie these two together by requiring programmers who benefited from GPL protected software to share their source code when they "distributed" the new version.
The notion of distribution was a simple notion that worked well when the typical coder was just an individual hacker spinning code and sharing it with his buds. Now the game is bigger, and much more complicated. We need to find a new mechanism that balances the freedom to hack with the responsibility to give back. We need to find a better, more clearly defined line to draw.
For the record, here are my proposals:
- Corporations (and everyone) should be required to release the modifications to their source code every six months to a year, if the modified versions are shared with more than, say, three people.
- Two piles of code are considered linked if one will crash or cease to provide more than 90% of its functions without the other. Note that this doesn't mean that any piece of software running on a GNU/Linux machine is considered linked to the GPL-protected kernel. If the software can be moved to a different OS, then it doesn't depend on the kernel.

He probably believes this, but IIRC, the main reason is that Richard Stallman believes that users of software have a right to the source so they can fix bugs. He got started on the idea out of frustration with buggy laser printer software he was using but couldn't get a copy of. I point it out because I'm intrigued by the idea of the practicality of [purely as an example] commercial software like Microsoft Office being sold for exactly the price and with exactly the terms that it has today, but including the source so you could make modifications yourself (with no right to redistribute).

Look at the issue from this angle. If Open Source(tm) software (as understood by Mr. Perens) is supposed to be such as superior development model it should survive on it's own merit without the necessity of licensing to protect it.
GPL zealots reject any suggestions of it being similar to the communist system but it is in a way. At least the fact that GPL enforces sharing is strinkgly similar to what communists did to the farming industry. They took all farms from the private hands (with or without the owners consent) and turned them into megafarms producing food that was shared amongst those who worked on them and the surplus (if any) would be sold to the shops. Eventually they 'phased out' private ownership altogether. How well that worked we all know now.
Sharing works at times but there must be a way for someone to bail out if they feel they gave more than they received and that they can do better outside of the commune. Some may actually contributed very little but may have the enterpreneurial trait that make them believe they can add value to what the commune produced and better themselves. And that's quite OK! The reason is that that's ok is because they REALLY have to add value. Think about it. RMS tells you that without GPL a company can 'steal' our code and turn it into a product that they sell for profit. The reality is that it will not work unless said company can add a lot of value to the original code in which case they deserve to make profit in my book. On the other hand if they just shrinkwrap and add a minor improvement here and there there is no incentive for the (informed) buyer to purchase the commercial version.
Communes and sharing always seem to work great in the beginning when the enthusiasm is there and all animals seem equal (GPL community). But after the initial excitement some notice that not every pig is equal because some pigs try to get a little more from the system without giving back (think all those who use GPLd software but never write/test/document any). Eventually someone tries to ride the wave and take the credit from good horses who just quietly code all the time (Mr. Raymond comes to mind).
So GPL doesn't benefit everyone. Just like communism it benefits those who are visible and loud but not those who work hard. A BSD coder can extend their code and one day decide they want to turn their effort into a product and they can do it. The freeloaders don't have the right to complain because they still have the old version which is free. For a GPL programmer this isn't an option, once communal always communal is the name of the game here. To put it bluntly: GPL protects noone and restricts the programmer while the BSD license gives the freedom to both the programmer and the user to do whatever they like.

As a professional software developer, I have been the beneficiary of quite a bit of software programming gems which have been given out as a matter of public domain. I have even taken these subroutines and incorporated them into some of the software that I've written for my employer. Unfortunately, by the nature of my contracts I can't release this software even if I wanted to (sense it is a work-for-hire... copyright issues and stuff). I've been careful regarding the GPL, and my immediate supervisor is actually looking forward to releasing updates to some GPL'd software under the GPL, especially as we are moving toward using Linux as one of our major platforms.
The point that I'm trying to make is that you can always try to get around any restriction if you really wanted to. Just look at the US Tax Code and see how some of the wealthiest Americans pay less, sometimes in absolute numbers, than many people making less money. They just hire a good CPA to find the loopholes to get out of the taxes. The GPL is no different, and if a company wants to use GPL'd routines and products, there is always going to be a way to get around the restrictions, even if they are upheld in court.
Probabally the most important thing to keep in mind with the GPL is to keep it up to date with current technology and changes in the computer industry. This article mentioned distributed software applications (where software runs on multiple machines... and I'm not just talking Seti@Home either), hacked interfaces (such as the Photoshop example), and stuff like Java or Flash applets where you run something once and then throw it away when you are done. The trick here is for the developer of the software to decide just how they want people to use it. What happens with quantum computers come along? Can you GPL a quantum machine? How? What about a neural network design?
The GPL needs to be updated from time to time, and the legal profession has long been slow to react to changes in technology. As long as the GPL stays in the hands of the technology developers (working, of course with lawyers.. but I degress) I don't see that this will be much of a problem.

Easy answer to the distribution question (Score:3)
If you read the GPL section 3, it gives you 3 options a, b, and c to comply with the distribution requirement. If you meet option a, you don't have to distribute source to any 3rd parties as required by options b or c, the written offer options.
I quote the GPL preamble:
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.
So you have to give program recipients the same rights to source as you have, but you don't have to give non-recipients _anything_. Hypothetically Red Hat could take down their anonymous FTP servers and distribute only on CD-ROM's in boxes, so long as a copy of the source accompanied each binary or was available at a nominal charge (like magtape days of old), and their customers have full GPL rights. If a company modifies a GPL program strictly for internal use, then the source must be available internally, but not necessarily externally if they don't distribute the program externally. Limited "beta" programs by software companies are allowed, so long as at least the limited "beta" participants are provided with source on request and have full GPL rights.
I don't see where GPL is all that unclear about distributions. It can be looked at on a person by person basis. If you give a GPL software program to a person for any purpose, you must give that same person a copy of the source, either immediately or on his request, and a statement of his GPL rights, but you are not required to do anything for anybody else. Seems pretty tight to me.

Linking is the main ambiguity, not distribution (Score:1)
But the linking clause is really hard to figure out. Any code depends on abstractions (e.g., specifed by a header file, admittedly partially), and the code doesn't really care whether the implementation of that abstraction (e.g., a library) is GPLed or not. Actually, the header file might be GPLed, too, but the code doesn't care about that either. foo.h might or might not be GPLed.
And, of course, a script links programs together in a different way.
My view is that the LGPL is a viable way of looking at the software world. The GPL wants to limit usage only by other GPL code, but again code doesn't really care about that. I guess RMS sure cares and that is why not much change can be expected.

It seems to me that the GPL tries to balance the freedom of ordinary users, business and free software developers, with a heavy slant to users and developers. With all sorts of possible conflicting "freedoms" to maintain, arguing which license is most free seems rather silly.
Be real. How the heck you can sell software that anybody can copy afterwards ? There is no example proving that a company was able to survive following this model.Perhaps not. But the fact is that GPL software provides a resource for all sorts of businesses whose primary business will not be selling modified versions of the software. How many companies are saving money by using Linux servers or in-house modified versions of GPL software? And in any event, most programmers have jobs working on in-house, unmarketed software anyway; this is the largest part of the software "market". They are getting a lot of free help and IMO companies shouldn't look a gift horse in the mouth.
IMO, the real strength of the GPL is in areas where issues of vendor lock-in and interoperability are so compelling that you are forced to wonder if it's a huge loss for consumers for companies to be selling proprietary versions of that type of product at all. This includes proprietary OSs with hidden API calls and word processors with poorly documented document formats. Core functional software of a computer shall be GPL; or I'll never use it. A library shall be LGPL; or I'll never link to it. And all other software I use of what license please God or its developers.

That's certainly what software companies would like us to believe. My view is that it (used to be) just like buying a book: buying a copy of a book doesn't give you the right to publish it, any more than buying a copy of Photoshop gives you the right to publish it. What you do get, though, is the right to use it for its intended purpose. In the case of the book, to read it. In the case of Photoshop, to run it.
It gets hairy because you have to copy software (to hard drive and/or memory) to run it. So, the software companies decided to try to change things around so that instead of buying a copy of Photoshop, you are buying a "license to use Photoshop." Never mind that you still buy a copy of Cryptonomicon, not a "license to read" Cryptonomicon. Then, after people get used to these little pieces of paper stuck into the software box pretending to be binding contracts, you just pay off some policymakers, and *poof*, they suddenly ARE binding contracts.

FSF statement on GPL "loopholes" (Score:1)
The general proposition on which Wayner's comments rest is that there is ambiguity concerning the meaning of "distribution" under the GPL. The first thing to be said is that the GPL is a copyright license, and when it refers to distribution it is using a term of art. "Distribution" under the GPL is distribution as copyright law understands it. Many people use the GPL to distribute software in many different places, but in what follows, for the sake of simplicity, I'm going to assume that the program being distributed is a copyrighted work of the Free Software Foundation, such as emacs or gcc. I'm also going to assume that the applicable copyright law is US copyright law. What I'm going to say is more general, but this will do for illustration.
To begin with, some of the problems Wayner associates with ambiguity about distribution are not about distribution at all. These problem are about whether code is part of a single GPL'd work when it is meant to communicate with, or operate in sequence or in parallel with, GPL'd code.
These questions are not being raised for the first time, and the Foundation has a single consistent position. Code which is statically or dynamically linked to GPL'd code constitutes a single derivative work of the GPL'd code, and must be distributed under the terms of the GPL. Code that is not linked to GPL'd code, but is distributed as part of a "mere aggregation" of works is not subject to the GPL, as section 2 makes clear. So when Wayner says that
he is describing an aggregation of works. If one or more of them are GPL'd, they must be redistributed in keeping with the GPL. Other works that are part of the same aggregation are not covered. The same is true with respect to processes running simultaneously, whether on a single multiprocessor cluster or in multiple machines communicating across a network. In order for code to be covered by the GPL it must be part of a work derived from GPL'd code. If it is aggregated with GPL'd code, or communicates across defined interfaces with GPL'd code, it is not part of the same work.Wayner presents a lengthy example concerning a weather database the purport of which isn't clear to me. The point seems to be that data produced by a GPL'd program might also be employed, through ordinary open network protocols, by non-GPL'd code. This situation also presents no ambiguity under the GPL. The GPL, again, is a copyright license, and it ony applies to copyrightable works which authors or assignees chose to license under its terms. Data compilations are not in general copyrighted works, and data produced as a result of the execution of GPL'd code is not in general subject to or controlled by the license on the code that produces it. There is nothing to prevent someone from writing and distributing non-GPL'd code that makes use of data produced, whether in real time or in stored form, by GPL'd programs. And there is nothing that prevents people from passing data between GPL'd programs and non-GPL'd programs, or from selling combinations of programs or services that mix GPL'd and non-GPL'd code.
Some of the questions Wayner raises are, however, about distribution. They are not more difficult than the non-distribution questions, but the legal background should again be slightly clarified.
Emacs, for example, is a copyrighted program, and unless you have a license from the FSF to engage in "distribution" of emacs, you can't do it at all. Under 17 U.S.C sect. 1001, the definitional provision of US copyright law,
So that's it. Anything that constitutes selling, leasing, or assigning a program within the United States or for ultimate sale, lease or assignment to an end user in the United States is distribution. As you would expect, there are loads of cases explaining what that implies in particular factual settings, and as you would also expect, those cases by and large take an expansive view of the copyright owner's right to control distribution, so doubt is resolved in favor of inclusion.Against that background, let me take up the specific questions Mr Wayner raised.
Not quite. MegaSoft is not yet distributing its modified emacs to consumers. Its internal modifications are covered by the GPL, however, because it is copying as well as modifying the software, activities which are only permitted if you have a license, and the terms of the license specify what MegaSoft must do. If it keeps these modified copies on its own computers, it has no further responsibilities under its license. If it allows employees to remove the copies to their own computers, it is then engaged in distribution, and it must provide source and allow those employees to redistribute the modified software under the terms of the GPL.
The same principles explain the situation regarding acquisitions and divisions of the MegaSoft Corporation, as well as the question supposedly presented by the free software assets of the company in the event of insolvency or sale. All the code is covered by the GPL from the moment of its copying, modification, or distribution, and any distribution must occur under the GPL's terms.
Wayner also asks about the embedding situation, presenting the example of Tivo. Tivo distributes a quasi-embedded system in which a free software kernel is used to execute unfree software. This is an aggregation of components, and Tivo is responsible under the GPL for the compliant distribution of the free software components of that aggregation. It is not responsible for releasing any of its own code under the GPL. The test is not whether the user can "pry" them apart in the particular circumstances of an embedded system.
These situations present no problem. Under the statute, leasing a work is distribution, and such technical arrangements are plainly covered by the GPL. Anyone offering execution access to GPL'd code, or code based on GPL'd code, must do so in a compliant fashion, wherever the leased copy is delivered or executed. Maybe we can clear up this confusion most easily if we step away from software for a moment. Let's use a copyrighted movie instead. From the point of view of what constitutes "distribution," is there a difference between broadcasting a pay-per-view movie over a cable system, so customers only get to watch the movie, or selling them the movie on videocasette? No. Both are distributions, and in both cases the entity making the distribution must have a license and comply with its terms.The most important thing to note about all these situations is that the "loopholes" Wayner is wondering about don't have anything to do with the drafting of the GPL itself. The GPL simply uses the concept of distribution defined in the general copyright statute. If there is a "loophole" it is a matter of general copyright law and the GPL is neither more nor less affected than any other copyright license. Wayner has kind things to say about Richard Stallman's drafting, and as the lawyer who has assisted the FSF for a decade in the use and enforcement of the GPL, I entirely agree with him about the document's elegance and utility. But he gives the GPL too much credit and assigns it too much blame when he supposes that the questions he is asking are questions about the GPL and not about copyright law in general. Fortunately for copyright law, it is not quite as fragile a system (in this respect) as Wayner seems to think.
I also feel I ought to comment, on FSF's behalf, on a statement made in the course of the discussion by Matthew Smith:
This proposition is not correct. The person who holds the copyright on a program can choose to license it under the GPL if she wants, but when she does so she can also license it, simultaneously or sequentially, on non-GPL terms. If she later wants, as Mr Smith suggests, to enhance it further as a non-GPL product, nothing whatever prevents her from doing so. She owns the copyright and is not somehow bound by the terms on which she licenses to others. The version released under the GPL is still free, of course, and can be modified and redistributed by anyone else. Those people, who do not own the copyright, cannot make their modifications proprietary. But that's because they have to obey the terms of the license that allows them to modify and redistribute in the first place.I don't happen to agree with the way Mr Smith threw the word "communism" around. As I have mentioned in an essay on these subjects that a few people may have read, called Anarchism Triumphant: Free Software and the Death of Copyright [columbia.edu], I think there are closer political analogues to what's going on here. But in any event it should be clear that people who choose to employ the GPL are not having their farms, their computers, or their programs forcibly collectivized.

Nothing in the license requires a Freshmeat announcement, or postings to the correct newsgroups or maillists (although this is encouraged!).
3) I thought the GPL explicitly dealt with content editing. You can edit proprietary documents with Emacs, compile proprietary code with gcc, and store proprietary information in MySQL. Just like you can write public domain documents in Word, compile GPL code with Visual C++, and store public information in Oracle.
4) There are gray areas still- just not the ones you list. Consider a GPL'd Java program- can I take pre-compiled
5) There is a lot of concern, and rightfully so, over this legal challenge. But a license which isn't defended is tantamount to no license whatsoever.
6) Do you think your average contract lawyer can write good code? Then why do you think that _you_ can write a contract that will hold up in a court of law if you're not a contract lawyer? The one huge advantage the BSD license has over the GPL license IMHO is that it has already stood up to the worst a large corporation (AT&T) could do. But of even greater concern to me than the future of the GPL is the horde of programmer-licenses that have shown up. How many of them have even been run past a contract lawyer, let alone a court of law? How many of them are just the pseudo-legalesse of a programmer way out of his depth and not knowing it?
The more dangerous legal challenge to open source may not be to the GPL, but to all of the programmer-licenses out there. But what of Apache or Perl? Perl's "pick your license" stunt makes it (mind you, IANAL) seem more vulnerable- at best, any action which is legal under either license is legal (i.e. the set of restricted behaviors is the intersection of the sets of restricted behaviours of the two licenses).

What does it matter to the worker that he or she doesn't have the source code to some proprietary enhancement his or her company made to some free software? Having access to the code would not mean that the worker could give that code to outsiders; it would only mean that the worker could perhaps do his or her job more effectively, in order to make more money for the corporation and make it more competitive.

This is another example of the simplistic and fallacious thinking of the GPV apologist. A more likely scenario one in which, of features z,q,r,s,t,u and v, only q and t are truly worthwhile. While XF is implementing these, they are also implementing a,b,c. It may be that the authors of XP really want b, so they have to integrate it. As the two codebases become more divergent it becomes increasingly more difficult for XP to maintain their separate enhancements. The cost of this maintenance may actually cause XP to contribute back to XF (this has been known to happen in the real world).
Of course, hypothetically, it could be that XF is incapable of anything more than copying XP's enhancements (as is the case with much GPV'd software, which tends to stagnate when there's nothing left to copy), in which case they deserve to lose and might as well pack it in.
Question: if XFree have such a problem with their license, why do they prefer it to the extent of refusing to allow any GPV'd code into their distribution? And why do the free BSDs only grudgingly allow GPV'd code into their systems, and almost always only when there is no free alternative? And why aren't the BSDs far behind Linux in most respects, instead of a little bit ahead in many and far ahead in some?
I disagree. The real purpose of the GPV is to allow the original contributor to eternally profit, albeit in a warm and fuzzy nonmonetary sense, from the creativity and resourcefulness of others. This is the real reason companies don't contribute to GPV'd software unless first bludgeoned by RMS, Bruce Perens and their teeming minions; there's proportionately very little in it for them, a good idea often being worth more than an initial codebase. That good idea may only be salable for a year or two, but the company's inability to build it on GPV'd software renders "contributing back to the community" at a later date a moot point.

I think you've got a strange idea of what "exploitation" is. What is given away cannot be stolen.
I think that the BSD and Linux kernel developers, and the members other Free software projects would characterize that "exploitation" as "use." All sofware was written to be used by the people who have it. The GPL doesn't dictate how you use code it licenses. It does tell you what you have to do to be permitted to distribute the code, or code based on it. This is something that you cannot do at all with most software.
What developers are saying, in a sense, when they release their code under the GPL, is "This software is the best damned thing out there, or at least, we think it has the potential to be the best (at whatever). Please use it. Please read the source, and make changes to it. Use whatever changes you make. But we made it, so if you want to distrubute your changed version, you must follow our terms, which are stated in the GPL."
So, corperate use of Open Source software is no "exploitation." It is a use of the software, probably as the it's author desired (though not always). The author's decision to use the GPL to distribute his code gave his permission to use it. Apple using BSD or an ISP using Linux and Apache, all are perfectly valid uses.
None of this addresses the issues of what the GPL should protect, rather than what it currently does. I think that future versions of the GPL should address issues surrounding networked use of software, and if such uses should cound as "distribution." I think they should err on the side of requiring source to be release more often, rather than less often. Bad source doesn't hurt anyone, but binaries without source could do just about anything (literally). I think source should be made available inside corperations when they use versions of GPL'd code (though employees might be prevented from distributing that source outside the company). I also think that some types of networked software should be considered distributed when they are used.
Anyway, I'm sure the GPL will gradually evolve as views on Free Software change. I hope it will always remain true to it's underlying philosophies.

huge loophole prevents commercial OSS work (Score:2)
However, it seems that it is not clear that operating a web page with software is considered a distribution under the GPL. I think this is essential if the GPL is to have any meaning whatsoever for web applications. As an example, consider the case of MySQL. Their old "free for non-commercial use" allowed corporations to run a MySQL database behind a webserver for free, because that was considered "internal" use, and not a redistribution. Although that allowed MySQL to get a significant market share among, say, mod_php users, it probably meant a lot of lost revenue for their parent company.
Now, since their parent company didn't really care (AFAIK) about this lost revenue, it was no big deal, but for a small company like mine, this could be utterly disastrous. OTOH, we have a pretty substantial HR application that I think the OSS community could really benefit from. Maybe it could be integrated into a scheme like the GNU Enterprise [gnu.org] suite.

There is little question as to what distribution is and isn't. If the code is given to the public, it is distributed. The answer to your MegaSoft question is easy: no, it is not distribution. These supposed problems you bring up aren't problems or questions.
Using some software to distribute information on the web is not distribution, and should not be treated as such. The web is no different than any other process. If I edit a GPL'd mail program, and use it to send mail to the outside world, must I give away my changes? Of course not. So don't pretend that is any different from using GPL'd software on the web, because it isn't.
Consider your weather database example again. No modified GPL'd code is being distributed. The fact that it uses GPL software is entirely irrelevant. Using a database is not the same as linking a library. And actually, I'd argue that you couldn't legally enforce that linking to a GPL'd library makes your code GPL'd anyway. It is a separate bit of code. It is used as intended. Linking to it does not necessarily constitute derivative work. That makes no more sense than saying that code written with Emacs on Linux compiled with gcc must be GPL'd.
In other words, I think the LGPL is rarely used because few people see it as necessary.
Two piles of code are considered linked if one will crash or cease to provide more than 90% of its functions without the other.
If you want to absolutely kill the GPL and perhaps free software altogether, this is a damn fine way to do it. Basically everything that relies on Linux, Perl, gcc, etc. would now be forced to be GPL'd (except for those users who opt for the AL under Perl). Anything that relies on Postgres or MySQL is GPL'd. This is absolutely nutty and unreasonable. You think Linus would continue to use the new-and-improved GPL if this were the case? Not likely. He wants people to use Linux, not be trapped by it.

No. Perhaps open-source advocates are. But open-source != free software. Stallman's position is that free software is better morally and ethically, not economically. In fact free software may very well be worse economically, but like other things like foreign aid, and social welfare, it is the Right Thing to do. However, coincidentally, free software under the moniker "open source" has actually turned out to support a decent economic model. This is what open source activists trumpet. However, to free software, this is a secondary and beneficial side-effect, not the main reason. The point is that Free Software is Good. Not that Open Source can make us Rich and Famous.

If I license (loan, rent, whatever) you software, as a corporation, which is technically a legal "individual", have I actually "distributed" software to you?

I think this comparison is flawed. The GPL doesn't force anyone to hand over their code. And once you've joined the so-called Free Software community no one can stop you from leaving. You are also not prevented from writing proprietary software at the same time (as long as you don't mix the two.)
However, once you release something under the GPL you can't then go back and make it proprietary. This is similar to writing code for an employer (lets say a corporation in the capitalist sense.) If you've chosen to write some code for them in exchange for money you cannot come back to them later and claim that the code belongs exclusively to you.

------------------------------------
This will discourage people from writing software for the Linux platform. Virtually all programs contain some system-level function calls, and some of them are Linux specific. No company can remain in business if they are forced to give the source code of their primary product away for free; none of the companies selling Linux distributions are even remotely profitable, even though they do sell media and service.
This clause, alone, will discourage people from supporting the Linux platform. Let's say a company wants to release one of its own products under the GPL and sign the copyright over to the FSF. If they have other software that interoperates in any way with the portion they want to open source, they cannot sell it, and must OS those code-bases as well!
The GPL should allow a company the flexibility of developing proprietary software that interoperates with free software. Otherwise the GNU/Linux platform will stop receiving the corporate support that it has in recent months.

To these people I suggest a)you're being a bit arrogant and stupid (I'll let you figure out why), and b)you're forgetting what makes open-source software "better". Why would someone be able to make money off your program by turning it proprietary? The open source version is free - it's got more development power behind it, it's more responsive to users, etc, etc.
Which leads me to the goal of the movement - free software for all. What's the best way to achieve it? Throw off all proprietary strategies and start out-producing! After, aren't we saying that open-source is superior as an economic model? ie, it's a more productive way to produce
high-quality software. Well, stop trying to win the game by "cheating" (ie using proprietary strategies like the GPL), and start winning by burying them.
Yes, if you see parallels between this and capitalism vs communism, then you're right. However, I see OSS as the new capitalism - in the sense that it is a more efficient system and will leave the old capitalism behind.
I think the GPL played a needed role in getting the movement jump-started. But, I'd like to see it be phased out by the community. I'd like to see a new license developed that, instead of putting restrictions on people, it merely informed them about the software - about where it comes from, where to contribute to, who the maintainers are, where to get tech help, etc. Not really a license, I know, but stuff like that could be standardized to good effect.
A good migration path might be for more and more developers to start using the LGPL, and then as more time goes by, just use the non-license, or even public domain (I don't like public domain as a name because it implies it's just "out there" without a specific group of people that maintain it).

Of course it's not better for the users to have no choice, but it's better for the users to have both.

The GPL is fairly simple. Live and let live. Or, more to the point, code, and let code. The release of the source code with the program is the heart of the GPL. As is giving those GPL rights to individual users when you release the code. In fact, every peice of code originating from a GPL core is supposed to be released under the GPL.
Manufacturers and software corporations who do not wish to release their source code, should not attempt to fall under the GPL. Such mandering is simply a marketing ploy to them, and it defeats the purpose, and the intent of the GPL.
Software manufacturers have to make money to stay afloat. No problem. They can sell their merchandise under the GPL. There is no provisions with either the GPL, or the FSF's mission that says you cannot make money off of your software. They only say that in order to release it under a GPL, you have to abide by the "un" restrictions of the GPL.
Or, in black and white, there should be no problem, because those with problems (with the GPL) shouldn't USE IT.

Re:My Proposal (Score:3)
In principle, I agree with you. However, while I believe that many of the so-called ambiguities in this article are not valid, this issue - 'release to specified individuals only' could be a real hotbed of controversy. Example #4 (below) is the real killer, but you need to ride the slippery slope to see how it could read in court.
For the sake of argument, let's imagine a GPLed communications program that has been modified to use a new unpublished crypto algorithm that the author doesn't want to release yet (or may never want to release). Maybe it's "security through obscurity", "NSA paranoia", or a real breakthrough -- it doesn't matter. I'll discuss two cases: a corporate modification and a 'lone hacker' modification, since different precedents will be based on different programs
1) A corporation creates this program to access its proprietary in-house system. It makes the program available to its employees, binary only. This is internal use - no source release required
2a) The corporation now supplies the program to contractors and consultants. Note: this is controlled release, but the recipients are not company employees. (Almost any internal-use program will end up being used by consultants or contractors at some time.) By your argument, this would be a mandatory source release, but I doubt a court would agree, due to the client-agent relationship and the specific need to access the internal corporate system.
2b) a private individual writes the above modified program to controll access to, say, his private anti-gov't website. He gives copies to relatives and a few close friends. Are blood, friendship, or academic ties enough to allow him to consider this 'internal use'? Unlike a corp, where individuals can be 'parts' of the 'legal person', he is dealing with 'outside' people.
The catch in 2a and 2b is limited release. Many prominent Open Source programs were 'private hacks' that grew into something useful and then released to the community. Not everyone wants to open themselves up to criticism until they are reasonably sure they have something good.
NOTE: The 'open source' provision of GPL only guarantees source to those who already have the program, not to the universe at large,
Limited Release is a slippery slope...
3a) The company makes the program available to a partner company on a project. Arguably still 'in-house' in a court's eyes
3b) The company makes the program available to a consortium (or assigns the program in its entirety to the consortium)
3c) The individual uses the cool program he wrote for personal use to do neat-o things at work (either as employee or consultant) but he uses it as a personal tool and doesn't install it permanently on their system
3d) The individual's client company insists that he install the program permanently (or sign over his rights to the program for a fair fee) on the grounds that the contract isn't fulfilled if only he can diagnose/repair the system. What rights can he sign over. if you believe he had the right to do 3c above, why can't he assign that right? Under copyright law, he can assign *all* his rights.
There are many other examples, but I'll conclude with one final-- The Horror:
4) a company writes commercial software, which it does not *sell* to the consumer, but allows them to *use* under a contract or license, either temporary or permanent, while retaining full ownership, and perhaps even the right to shut it down remotely
SOUND FAMILIAR?
Is this distribution? A loan? A limited access? "Use within a specified business relationship"?
Look, I think 90% of us would agree what it should be, but I hope you can now see how it *might* be seen after several years of precedent

As long as there are enthusiasts who are willing to contribute good code for the common good there is no need for enforced sharing. Sharing which is enforced by law is called confiscation as far as I'm concerned. Sharing must be voluntary to be successful. So what if company X, Y or Z forks a project and makes a commercial version. If the free version developers think it's neat they'll add the feature to the free version if it's something they want. On the other hand the company can make the software successful and will probably 'pay' the original developers in one form of another (suggesting bug fixes, giving away some of their code or even sponsoring the developers). I don't care about the end users half as much as RMS does. Because 99.9% of them just use the code and don't even bother to send a thank you note never mind contribute something positive I think those should simply be grateful for getting a freebie.
On the contrary the GPL license states that 'once free always free' which means that companies must watch closely what they're doing. No company can ever make profit from GPLing their code it gives them nothing apart from good PR because the minute the code gets GPL'd they waive their right to make any sensible profit off that code and we've yet to see a single company make money selling support for GPLd software. Free software and commercial software needs to coexist. Free software shouldn't and can't replace proprietary packages. I lik to have both options.

Remember, GPL's only power comes from copyright. Under copyright law, a program that links to a library is considered a derivative work from that library. A program using code from a copyrighted program is also a derivative work. But a program that merely accepts data through a pipe from a copyrighted program is *NOT* considered a derivative work. And of course, copyright law allows the author of the original work to dictate exactly under what situations the work can or cannot be copied -- or, as the GPL puts it, "distributed".
The real problem, though, is client/server based programs -- which I think the author was trying to describe, even though I don't think he did it well. As an (unrealistic) example that I find easier to understand than the weather thing, I can take a GPL X11 program, say Emacs, make some modifications to it without releasing them, and then type "DISPLAY=some.other.computer.com:0 emacs", and the person at some.other.computer.com using my modifications to Emacs doesn't have the source code to those modifications. I can even charge for this service.
And of course this problem would more realistically crop up with something like a part-GPL CGI backend to a web site. Web sites may eventually have the functionality of client-side programs, and unfortunately the more powerful HTML is, the less powerful the GPL is, because GPL code can be mixed with proprietary code in CGI's without giving any code back.
The only solution to this problem is to do what the GPL has of yet intentionally stayed away from doing -- restricting the ways in which a program can be used (rather than copied). The legality of this is questionable (or at least some people consider it questionable), but it is the basis of software click-through/shrink-wrap licenses, so it's already common practice.

1.) Corporations (and everyone) should be required to release the modifications to their source code every six months to a year, if the modified versions are shared with more than, say, three people.
Besides the general unenforcability of this because a.)We will need GPL auditors swoop down on random Fortune 500 IT departments to do on-the-spot checks like for AutoDesk and other expensive proprietary software) b.) The specificity of certain extensions makes them meaningless to anyone but that corporation. (the company I work for has several e-lisp packages for Emacs that simplify many tasks specific to our project) Asking companies to GPL internal code, would simply make the GPL more of an anathema in the corporate world. Which would suck since I use a lot of GPL software at work.
2.) Two piles of code are considered linked if one will crash or cease to provide more than 90% of its functions without the other. Note that this doesn't mean that any piece of software running on a GNU/Linux machine is considered linked to the GPL-protected kernel. If the software can be moved to a different OS, then it doesn't depend on the kernel.
This seems even more unenforcable, how do you quantify 90%? This also seems unreasonable, if I have a script that uses grep in several places to perform a complex task, do I have to GPL the script or all the code invoked in the script, isn't a script by definition something that probably serves a specific task for a specific situation....what would be the point of asking for all scripts that invoke or use GPL code to be GPLed? Also about the "one will cease without the other argument", what exactly will this mean... if I can write a program that uses libraries that are either GPLed or proprietary, does this mean that I have escaped the "one will cease without the other" argument? On the other hand if the author actually means that the GPL code used should be extracted then the program run, more than likely the program will cease to work. After all I have lots of code that is over a thousand lines but would cease to exist if three or four lines would have to be erased.

With the rise of the web in general and Application Service Providers specifically...what happens when a website uses modified code to serve it's pages?
