Why don't they just put into the license, plain and clear, a phrase like " The company Microsoft (or whatever it is in legalize) can not use or interact with software that is covered under this license unless it is by its customers using their OS.." etc. If everyone knows they wrote some parts of it to go against the actions of one company, why try and do it so vaguely. After reading the GPLv3 it is very clear some parts of it are politically motivated. I don't even agree with it on some points, but it's not my license, so they should just put in it what they want just like they already have. Right now everything I do I issue no copyright on and am happy if someone else wishes to use anything I may have thought up.
