Absolutely. I didn't mean to say he "only" changed my view, in case that's the impression. He is a great man, the entire (digital) world is built on his legacy so to say, yet barely anyone knows about him.

PS: little anecdote as I once went to an Apple Store and scrolled through the software licenses in the settings on an iPad of iOS and found one crediting Richard Stallman as the author. I just left it like that, thought it's funny having his name on an iPad in the Apple Store :p
