Many view Stallman as a wingnut, but he is a useful wingnut.
In any battle, there are the extreme personalities that lead the charge.
Without Richard Stallman, there would be *no* free software movement, I have no doubt about that.
I find it interesting though that many people think that his views are extreme in the freedom realm. They actually echo many views that I have in my own life.
I shred all receipts: all of them. I avoid parking meters that require me to identify myself. I use a RFID card for transit but I despise it because a machine somewhere is recording all my movements, as opposed to the disposable, anonymous scratch card transit pass that I used to prefer when they were available. Cameras with facial recognition scare the shit out of me.
And it worries me that few other people feel the same.
