Like I said, there's no line and with all respect, I think you're still trying to draw it. Keep in mind there are even such things as self censorship and soft censorship. It doesn't matter how you dress it up or what reason you have for doing it, censorship is censorship. You don't see the military asserting any right in the second edition, because that's the one that has all the unwanted bits already taken out.
Note that I not condemning it or making any assertion about its morality.
That's going to be kind of hard to do since at least some of the GPL software is actually copyrighted by Czech programmers.
I'm not even sure what you think that would accomplish apart from ruining lots of people's livelihood and creating substantial profit for the lowlife that came up with the draft in the first place. And how would you implement that? Who would have the right to decide who's on the "pariah" list and who's not? Would you still agree to this if the USA made the list?
