Linus got away with being an abusive asshole as long as he did because our culture objectifies men by only valuing men for what they can DO.
As long as a man is USEFUL TO OTHERS, nothing else matters.
Linus could have been a rapist who stayed in shape by punting puppies, and nobody would have said anything as long as people thought Linux couldn't go on without him.
That's no longer the case, so Linus is no longer immune to criticism.
