What about the part of his activism where he makes up stupid baby names for everything he doesn't like, shouts at all his colleagues and eats skin off his toes?
The attacks on his character and the noisy tantrum Google had over AGPL a few years ago (e.g. even banning it from their own version of github for a while) are manifestations of the same desire to see him and his movement nullified.
A watered down FSF run by an inoffensive do-nothing would be a better outcome for big tech than leaving him in charge. Hence the all the attempts to cancel him, including via cynically hijacking #metoo.
