I view the FSF as software socialists, as in they have a utopian view of how things should be and everyone should buy in and give all of their stuff to everyone else for the good of the community. I also view socialism as an impossible ideal to achieve. In my opinion, all attempts at socialism have ended in communism, where the ruling class tells the people they have socialism but in reality the people at the top of the chain don't buy into it and live much better lives.
Finally, I used the prefix "pseudo" because obviously we're talking about software and not the rise and fall of empires (although Facebook is sort of a digital empire) so I didn't want to attach a full-on label of "communism" to it.
edit: I'm sure someone who has studied politics way more than I have will come in here and point out that I don't know my ass from a hole in the ground, and that's fine. I bitched about the FSF and I feel better so my mission was accomplished.
