I'm a feminist,and can't stand a lot of the stuff that goes on on reddit.
That said, censorship on that website is rampant. Reddit is trying to monetize, and that means stifling speech, especially that speech critical of corporate governance.
The issue isn't as black and white as you make it. There are people with legitimate grievances. And there are people who are being sexist pigs.
Reddit will tell their userbase that the whole fiasco was Pao's fault. They will tell the board and investors that the userbase is sexist.
They think it's win win, but they are on a sinking ship.
