You're wrong. The ENTIRE front page of Reddit was all talking about the AMAgeddon/darkening/blackout, then within a few hours, it was back to happy cat pictures. If you look at /r/blackout2015, it's not because people stopped talking about it. It's because the posts were fucking hidden by the admins. The posts still exist, and some have upwards of 10,000 upvotes. Only to be trumped by cat pictures with 500 upvotes. If that's not fucking censorship, you should get cracking on finding a dictionary.

Further, hundreds of users were shadowbanned for posting against Pao. Subreddits against her were closed. Admin were forcing top default subreddits open despite their "mods = gods" stance of the past, asserting that mods get to mod their subs the way they want. This is all censorship, and it's biased censorship at that. /r/fatpeoplehate was banned for "brigading", that is, leaking out of that subreddit and harassing users elsewhere. There are multiple Feminist subreddits who do this very thing, on a day by day basis. They aren't banned. Their mods and users aren't banned.
