An anonymous reader writes "Groklaw has a transcript of Eben Moglen's Harvard Speech + Q&A up. Good Stuff. During the Q&A he made a good point to think about: 'We stand for free speech. We're the free speech movement of the moment. And that we have to insist upon, all the time, uncompromisingly. My dear friend, Mr. Stallman, has caused a certain amount of resistance in life by going around saying, "It's free software, it's not open source". He has a reason. This is the reason. We need to keep reminding people that what's at stake here is free speech. We need to keep reminding people that what we're doing is trying to keep the freedom of ideas in the 21st century, in a world where there are guys with little paste-it labels with price tags on it who would stick it on every idea on earth if it would make value for the shareholders. And what we have to do is to continue to reinforce the recognition that free speech in a technological society means technological free speech. I think we can do that. I think that's a deliverable message.'"

With IRV you could vote for an independent without being concerned that you might 'spoil' an election, or 'throw your vote away'.
More importantly, you could vote for different independent, if the previous independent turned out to not represent your views, or the values he advocated at election.
Imagine being able to support Perot without risking Clinton, or voting Nader without risking Bush.

This is what I love about the GPL. I think everyone can agree, given that a peice of software has been created, it is better for society if everyone to has access to it. The only issue at question is whether by limiting access to the software, we can provide necisarry means and motivation for more software to be written. I look at the GPL as an experiment - if copyright really does provide necissarry means and incentive to produce software then GPL'd software will never be as good as proprietary software, and will reamain on the sidelines. However if GPL'ed software does surpass and surplant proprietary software, then it is proof that there is enough means and motivation to produce software without the burden of copyright. This is increasingly showing itself to be the case.
The FSF focuses on the first issue, and think that the negative societal aspects of proprietary software are so bad that it doesn't matter whether copyright adds incentive or not, proprietary software is still intolerable.
The OSI focuses on the second issue, and think that the only important thing about free software is that it is better than proprietary software, and have provided usefull theories which help explain why this is the case.
But the real clincher is that both issues are true - that not only is software copyright harmfull, it is also unecissarry. It is for this reason that I agree with the FSF in treating it as an ethical situation, because while I am willing to put up with some "necissary evil", there is no reason to put up with proprietary software in the long run.

At about an hour in length, it was quite good. I really recommend it, because it puts both SCO and the things you hear Stallman say into very nice perspective, and shows how terribly confused Darl McBride really is. In particular you should watch for Moglen's description of the problems with using Eldred v. Ashcroft to support the odd notion that the GPL is unconstitutional. Darl doesn't realize it, but his argument indicates that he and the FSF are actually on the same side of that Supreme Court case.

... and one relevant to a much-debated topic here on slashdot.
Moglen makes a very lucid explanation of why the apparently-more-free BSD license is less valuable to people who believe in freedom. He characterizes the the world of free software as a "self-healing commons", that cannot be appropriated, or destroyed, and points out that a BSD-style commons is much more vulnerable to being "proprietized".
The really interesting parts of his talk, though, were the bits about open hardware and radio spectrum, and their implications on technological free speech, and of course his extensive and detailed explanation of why he thinks the free software battle is essentially already won.
Even if you don't agree with him, Eben Moglen is a persuasive speaker with very deep and powerful ideas. Very well worth reading/listening to.

Stallman has done a great service to the community by keeping this aspect of the movement alive. I have had direct correspondance with him multiple times and he has NEVER failed to personally write back with elaboration on a point or a rebuff to an argument. He must have spent the majority of every day for the past 25 years spreading the case for Free Software one person at a time like that without compromise, which is how he has achieved what he has achieved and deserves respect in the community regardless of personal wranglings.
However, Stallman is so marred with 25 years of personal politics that it is difficult for him to inspire. It never seems like he can quite decouple the ideals of freedom of expression from a certain "I _AM_ THE IDEALS, RECOGNIZE ME, the GPL is the ONLY way to go" attitude.
If the entire community can be inspired to the real ideals of Free Expression, than the GPL itself would almost be irrelevant. Stallman has used the GPL as the glue to keep the community together regardless of it's beliefs on the issue of free expression, but this needs to be seen as an entirely secondary issue.
I hope to at least see Eben Moglen and similar speakers invited to more software conferences.

I do too, and I bet it will come to pass. But (from someone who attended the speech) there's something we should realize: Moglen and RMS are championing almost exactly the same principles and agenda. The differences are in how they serve the agenda: Stallman by writing code (in the beginning) and playing the visionary, Moglen by plotting legal strategy and fighting the legal ground war; and in their particular communication styles.
So while I agree that RMS's personality may be getting worn and he is somewhat tainted by politics, it is important that we see Moglen not as a less orthodox RMS, but as a new, and perhaps more effective, conveyor of the same fundamental message. It may help to note Moglen's pointed expressions of respect and admiration for RMS during the speech.
That said, Moglen did put the free software movement in a wider legal and intellectual context better than RMS usually does. Moglen can play the visionary very well if he wishes! Perhaps if we are inspired by Moglen, we can reconsider RMS with renewed appreciation.

Everything is automagically copyrighted? Fine. I'll explicitly license it to everybody. What are you evil people going to do, tell me I can't license what is mine?
Give them (or us, as I write a little free software here and there) twenty years more; the body of freely licensed knowledge will be so huge there won't be any benefit in anything proprietary. There will be so many musicians and artists licensing their cool stuff that we won't need to infringe on anyone's copyright to listen to good music. Those that try to say "Hey, come here and buy the right to hear this song" will face the question "Why? There's so many free stuff to hear I actually haven't got the time".

real history of term "open source" (Score:5, Informative)
According to "Rebel Code - Linux and the Open Source Revolution" by Glyn Moody (chap. 10), the term "Open Source" was coined in Winter/Spring 1998 (February 3rd?). Eric Raymond initiated the search for a term for this "free software" coming out, and later "open source" was decided upon. It seems they were looking for something less ambigious and more business-friendly than "free software". The term itself was originally suggested by Christine Peterson of the Foresight Institute.
regarding Stallman (quoting from the book)
"Richard Stallman always viewed this shift [from terms like 'free software' to 'open source'] with alarm. 'The open source movement is Eric Raymond's attempt to redirect the free software movement away from a focus on freedom,' he says. 'He does not agree that freedom to share software is an ethical/social issue. So he decided to try to replace the term 'free software' with another term, one that would in no way call to mind that way of framing the issue."
So it seems that, historically, there is something of a difference between "open source" and "free software"
Enligthening Q/A (Score:5, Informative)
Moglen: Ah, the software. .
Q: That's the kind of stuff I think I was more getting at with my question. So you have somebody who creates something useful but it has a zero distribution cost, and it's useful in a way that's not, not useful like celebrity, though I'm not sure, I don't think that's useful in some ways, but it's useful in the different sense that it takes a long time to create well.
Moglen: See, the programmers I worked with all my life thought of themselves as artisans, and it was very hard to unionize them. They thought that they were individual creators. Software writers at the moment have begun to lose that feeling, as the world proletarianizes them much more severely than it used to. They're beginning to notice that they're workers, and not only that, but if you pay attention to the Presidential campaign currently going on around us, they are becoming aware of the fact that they are workers whose jobs are movable in international trade.
We are actually doing more to sustain the livelihood of programmers than the proprietary people are. Mr. Gates has only so many jobs, and he will move them to where the programming is cheapest. Just you watch. We, on the other hand, are enabling people to gain technical knowledge which they can customize and market in the world where they live. We are making people programmers, right? And we are giving them a base upon which to perform their service activity at every level in the economy, from small to large.
[1:15]
There is programming work for fourteen-year-olds in the world now because they have the whole of GNU upon which to erect whatever it is that somebody in their neighbourhood wants to buy, and we are making enough value for the IBM corporation that it's worth putting billions of dollars behind.
If I were an employee of the IBM corporation right this moment, I would consider my job more secure where it is because of free software than if free software disappeared from the face of the earth, and I don't think most of the people who work at IBM would disagree with me.
Of all the people who participate in the economy of zero marginal cost, I think the programmers can see most clearly where their benefits lie, and if you just wait for a few more tens of thousands of programming jobs to go from here to Bangalore, they'll see it even more clearly.

As for those 13 herbs and spices... consider the following transcript from this article...
So let me tell you what I think the owners of culture were doing in the 20th century. It took them two generations from Edison to figure out what their business was, and it wasn't music and it wasn't movies. It was celebrity. They created very large artificial people, you know, with navels eight feet high. And then we had these fantasy personal relationships with the artificial big people. And those personal relationships were manipulated to sell us lots and lots of stuff -- music and movies and T-shirts and toys and, you know, sexual gratification, and heavens knows what else. All of that on the basis of the underlying real economy of culture, which is that we pay for that which we have relations with. We are human beings, social animals.
In there small way KFC is threatening freedom of speech. They've created a secret formula, and made it a celebrity. They own a piece of our culture, like George Lucus owns Star Wars, and that's how they make all that money.
As for freedom of speech, people will publish receipes, (and make movies), and others will take those receipes and improve upon them (there is no requirement to republish), and over the centuries we developed wonderful and complex delicacies and great diversity. KFC gives us a few types of food and they sustain their IP with marketing. Why is this restricted model somehow better for society just because it creates shareholder value in the pockets of a few?

And it's an idea that is 100% moose hockey.
Unlike the natural properties (things which are capable of being owned), ideas are not capable of being owned. "Intellectual property" is a creature of law, designed solely to encourage the fixture of ideas (not, crucially, the creation of ideas... the purpose of copyright and patent is solely to have people WRITE STUFF DOWN so that others can access it and use it). It's since gone badly off the rails, but that's the animating purpose behind all such laws.
You can't own an idea, any more than you can own the word "dental". You can keep an idea private, but that's different from owning it.
The fact is, that "moral rights" never even appeared on the radar screen of intellectual property until well after the current model of permanent ownership of the products of all human ideas came into being.
There is no theft in the "theft" of an idea, for the simple fact that my appropriation of "your" idea does not alter or harm your own idea one iota. My taking the "idea" under my control does not, in any way, affect the control you have over the idea. As a result, ideas are simply not capable of being owned, since the only purpose of ownership is the taking under human control of those things that can be controlled.
Sorry for the heavy Hegelian slant of this (I'm hauling my concept of ownership, incidentally, out of Hegel's _Philosophy of Right_). But in a nutshell, ideas are not things, and treating them as things is stupid.

Scarcity, according to Aristotle, is the fundamental principle of economics. If there's a limited supply of something and unlimited demand, then there needs to be some kind of rationing. Property laws provide that function.
A matter duplicator would force us to rethink our ideas about physical property because it would remove the scarcity issue. The Internet is forcing us to rethink our ideas about intellectual property for the same reason.
>whether the *creator* (or creators) of a piece of IP have the moral right to designate its usage
Well put. From a human-rights point of view, "designate the usage" means giving orders to the other six billion people on the planet about what they can do with a piece of "IP". From a utilitarian point of view ("greatest good of the greatest number") useful intellectual work should get spread as widely as possible. The compromise of copyright law was an attempt to ensure the greatest good given 18th-century distribution methods.
If I understand the rms position, it's not so much that it's bad to make money from software, but rather that it's bad to imprison the software and make money by charging for access to it.

While the purposes you outlined are correct, nothing was weakened. It's a use of the existing copyright system to ensure that the end-user is given the same freedoms (and restrictions) given the re-distributors. Those freedoms are the right to read the source, make modifications, and pass the code + modifications on to others.
Regarding patents: both OSS and FS allow patents to be filed. The difference is that FS requires the patent owner to license the patent for free and without much restriction (IIRC) to the end user, such that the end user's freedom to re-distribute and modify are not restrcited.
