This may well be true, but it wasn't the centerpiece of his cancellation. And if it is true, it hasn't been publicly articulated in any coherent way, as far as I can tell. I'm not saying that it isn't the case, it's well known that RMS can be abrasive. But if he was actually forced out for that reason, it seems like someone familiar with it should have written that up in some way.

I've seen a few off-hand accusations that he made women uncomfortable in non-specific ways. I can certainly believe that might be true, and may indicate some greater transgression lurking behind the scenes. But to my knowledge nobody has actually said what that is.
