Gamergate was a first mass reaction to corporations using idpol as a method of censorship for their gains. It started as some people noticing the incestuous relationship between game journos and devs and ended with both sides foaming from their mouth about danger of each other views safely forgetting the initial reason.
No, gg wasn't coopted or founded by "right" or whatever, if you say that, that means you take your info from shitlib mainstream sources. While there was noticeable presense of them, it was mostly because that on the other side there were liberals that americans like to call "left".
In fact it was only one of the many instances of corporation censorship happening, just the most noticeable one. Right now if you wanna see it happening again, i suggest reading some IT news, specifically about open source. Like Richard Stallman being fired from his post as FSF director because of some idpol politics, or putting pressure on Linus Torvalds same way, or getting rid of many guyd from OSI that support anti corporation stance. Porkies are using sjw as a tool for getting rid of the opposition. And gamergate was just an instance of that, but with a much bigger blowback than anticipated.
