I heard Stallman speak once about FOSS. He struck me as a very interesting person, but not very flexible in his views. Even if he's 100% "right" in the long run about how digital products should be completely free, his views are so polarizing that it'd be hard to interact with him long enough to understand his positions.
I think there is value in people like Stallman existing. I disagree with him in a lot of regards, but I think it's important for people like him to shift the "Overton Window" of software copyright a bit closer to FOSS. He's a disagreeable bastard, I'm not even sure he would dispute that, but a part of me does respect the dedication to the cause.
That said, I almost always use BSD or MIT licenses for my personal stuff; sometimes I use the Eclipse one because that's the default that Leiningen gives me for Clojure and I can't really be bothered.
Idealism retards the growth of most good ideas. I suffer this daily but it is an internal struggle and I structure my idealism to minimize the impact on others.
