I have no way of proving this anymore, since r/GenderCritical is banned and I didn't save an archive of my comments ... but there was a large discussion thread at the time GenderTrender got banned from Wordpress. It was in 2018, shortly after GallusMag revealed all the dirty details about Jonathan Yaniv.

It was all blowing up among GC circles and on social media, and random people were getting banned from Twitter and Facebook. Users were speculating about what was next.

I looked into Wordpress investors and the portfolios they maintained, which companies and boards they were a part of, and who they had invested in previously. I found a trend and commonalities. Among other things, Facebook and Twitter had been slowly updating their TOS and banning users over the prior year, Wordpress jumped the shark.

I predicted Medium would be the next site to start publicly censoring. Within a month or two, Medium released new TOS protecting gender identity, and started banning users.

Facebook and Twitter went all-in soon after, and stopped being passive and started aggressively making changes. Reddit had already been shitty, but I feel like their narrative accelerated right around then also. The groundwork had already been laid. Opinions that were not pro-TQ+ started being cancelled like an avalanche, and there was nowhere to turn because all the other major companies were doing the exact same thing.
