I have some karma to burn, so I'll say it.
Military use of Free software is in violation of the spirit of the movement. Yes, the letter of the GNU licences doesn't stop you doing immoral things with code, but it is clear that if I took the time to contribute a nice little program to the human race, it wasn't so that some bastard could come along and in use it to facilitate the blowing apart of other human beings. The fatigue-wearing bullies of some regime halfway across the world, be it in Korea, India, the US, Honduras or anywhere else, are not welcome to the fruits of my labour.
Any discussion of this matter which does not consist either of plans to stop this happening, or sighing wishes that things could be different, is completely missing the point, and a sign of a lack of civilisation.
