I don't think he is any more or less creepy than hundreds of others socially awkward computer scientists that I met over the decades. The difference is he has a position of power which he should never have for hundreds of reasons (not alone that he isn't good at it). He is the type of person who if I'd employ him I'd value him and protect him by keeping him in an off-site basement lab where he wouldn't even be allowed to open the door for the pizza delivery.
It's a huge problem when you're the public face of a movement and are also a mysogynyst. But this whole situation of wanting to cancel him speaks more about the FSF (who doesn't see a problem of bringing him back on to the board) and the other extremists ("blue haired social justice dweebs on twitter who hate him because they notice he is equally socially inept as them but has more power than them).
