The problem is GamerGate started with the attacks on Zoe Quinn, which turned out to be complete fabrications.
The real problem is that even if GamerGates's allegations about Quinn were 100% true, nobody cares if person A slept with person B for an obscure review of a game on some website. It is literally the least possible social sin; people who go through the express lane at the supermarkets with more than 6 items deserve more scorn.
The big publishers spend literally hundreds of thousands of dollars in advertising with the same websites and the self proclaimed guardians of journalistic ethics seem OK with it. This, along with the fact that the whole thing with Quinn was totally made up, seem to point to GG being a bunch of arseholes. I really want to believe that most of them are just morons who don't understand the game industry, journalism, or humanity in general, and are just misguided because I don't like to think there are that many arseholes around. But they just won't shut up.
