IMO, it should be the other way around.

The BSD license doesn't have such a protection, so I consider it unsafe, aka not popularly accepted.
You don't have to agree. That's the point: This is not something that can be summarized effectively in such a tiny little chart.

The USA was fairly close, after WW2, to making a bunch more nukes and carrying the war to the soviets. They were stopped partially because they couldn't afford the manpower to actually hold the country once it had been broken.
The USSR was fairly obviously looking to become the only superpower, and that would have been most quickly accomplished by destroying the USA.

That's a common misconception. As long as the user does not mess with the source, the GPL has no effect (except, of course, that the software is freely redistributable). These things only rear their heads if you want to modify the source. Users are not affected.
The irritating thing is that M$ are using this argument against using GPL'ed software vs their own. As long as you only use the software, not modify it, the GPL does not affect you - and it certainly doesn't harm your IP. That's only if you modify the software, which you couldn't even *do* with proprietary licences of M$ Shared Source.

We're a research-department an we're not supposed to create real products. We're creating several source-analysis and documentation-management tools, which might be "sold" to other departments.
Commonly used OS-projects are e.g. xerces, boost, python and wxpython, where we usually only contribute bugreports or small patches.
Some tools use proprietary libraries that we must not redistribute as sourcecode. (e.g. a C++ backend from EDG) So if we want to call GPL programs (e.g. cvs or some source-documentation systems) we must not make proprietary extensions to it. It doesn't matter if we put the modified program under the GPL, it would still violate the license, because such an extension would be only usable with other non-GPL programs.
The sad thing is, that some people prefer to pay for inferior commercial sourcecode instead of contacting the original authors in order to come to an agreement.
Instead of documenting the subtle relations between dozens of different licenses (as someone suggested) we should try to encourage a personal contact to the developers. If the author allows you to use his code under certain conditions you don't even have to understand the original license.
IMHO the problem is that PHBs are afraid of such agreements, and as long as there's a different solution they don't want to try something new.

People who make this attempt should be killed, and their work destroyed. Collaborators should be killed, sympathizers should be killed. It is unclear whether it is wiser to do it publicly, to discourage attempts, or covertly, to keep attempts public and make them easier to catch.

By using phrases such as "monstrous and evil" it suggests that you have already written these people off as such, and are not prepared to discuss the situation any further.
In particular, it suggests that any question posed to you will be answered with the same phrase.
Also, you have to be very careful deciding what is evil and what is not, because it changes as society changes.
For example, contradicting the Bible used to be heresy, a monstrous and evil act since you were seen as speaking out against the will of God, and what could be more monstrous and evil than that? So they used to burn alive the people who did it.
Nowadays, burning people alive would probably be considered as a monstrous and evil act, and depending on where in the world the perpetrators lived they would either be locked away for life, electrocuted, hung, killed in a gas chamber, shot, etc. etc. etc.
Umm... which in themselves are (IMHO) fairly monstrous and evil acts, yet considered perfectly fine in the circumstances because "the perpetrator was monstrous and evil, and thus deserved it"
(incidentally, I never suggested that "people opposed to [my] argument should be killed," only that people attempting or supporting attempts to destroy humanity should)
But your argument here suggests that creating AI will destroy humanity. Fair enough, that's your opinion, but not everyone shares that opinion. That means that there is a chance that you are wrong. So you cannot (safely, without any doubt of becoming monstrous and evil yourself) say that any particular group of people is trying to destroy humanity unless you know absolutely that it is there intention to do so.
If it isn't their intention to do so, then the best that you can say is that they are misguided, in which case you should be aiming to educate them, but you can't to this by imposing your view on them and forcing them to accept it (after all, they might be right and you might be wrong - you can't be sure), so the only way to do the education is to discuss the situation with the people involved and try to convince them that your argument is best, whilst being prepared to take the risk that their reasoning might be better than yours.
To conclude, that's the reason I don't take people who use "monstrous and evil" in their posts seriously
