RMS asks you to give something up: Your right to share a thing you made, under your conditions (which may be conditions even the receiving party agree on), nobody is forced in this situation, and then he calls that evil. I think that is wrong.
I love FOSS, don't get me wrong. But people should be able to say: I made this, if you want to use it, it's under these condition or I won't share it.
Again, imho the GPL is a blessing for humanity, and bless the people that choose it freely.
