I find the the surprising thing about statements like this that anyone who has dealt with him might not have been alienated by RMS. He's a serious pain to deal with.
Of course this is apocryphal (I mean: it's not apocryphal to me, I've tried to deal with him and I'd frankly like never, ever to have to do so again) and I have no statistics to back it up, but, well, seriously: if you've had dealings with RMS and not found him a really serious pain I'd like to know.
