I was working for Apple in the early 90s, and he called me evil. (A friend of mine, who also worked for Apple, was in the same room. To the best of my knowledge he didn't call /her/ evil. My assumption is that he didn't do that because she was attractive and single).
I can respect radical. Being a hypocritical asshole, I cannot.
What does this have to do with HN?
I use very little GPL software. If something is GPL 3 I really, really try not to use it; I'll buy a commercial package instead, or write my own (if that is feasible), or do without (ditto).
Stallman's radicalism can have the opposite effect that he thinks it does. His unreaonableness creates markets. Probably small ones, but they're there.
Working for Microsoft is still a job, not a lifetime decision. And attributing a job with "evil" sounds like a hyperbole (ignoring jobs that involve killing people, that's a different matter).
Don't be like Richard Stallman! Even Richard Stallman can barely get away with it!
I'd have put his beardy ass out on the street for that one, no lie. "Sorry dude, this is CLOSED SOURCE petrol, out you go".
Behavior like that, where Stallman immediately alienated a potential ally, does little but harm the free software cause. The only thing it enhances is Richard Stallman's reputation among a small (and probably dwindling) group of radical free software advocates.
