That's a really interesting argument. One could argue that the GPL is like the snake eating it's tail on the far side of liberalness. I'm sure this is not a new argument, but I'd never considered that the "polluting" of code with the GPL actually decreases individual liberty for the sake of communal liberty.

Again, not making a judgement one way or the other, but the world is nothing if not a series of bad compromises, and I suppose it shouldn't surprise me that the GPL and OSS in general is included in "the world" :)
