Richard Stallman

I've been taking some interest in the FSF as it relates to Linux. In particular, I've watched a few video interviews of Richard Stallman. I think he's right on many points, such as the idea that we're being tracked, and the chance for inclusion of backdoors in many software products, and that you can never be sure what's happening under the hood of closed source/proprietary code. I'm convinced that he's doing what he feels is right, and isn't just tooting his own horn. But as well, he seems to be taking extreme measures against what I think he perceives as enemies, whether they are or not in actuality. He won't ride a train because he doesn't want to use a cashless system.

Is he right? Or has his ideology fallen into the realm of conspiracy theory?
