As often happens nowadays, the valid complaints from GamerGate were conflated with the harassment that went alongside it, and so even mentioning 'ethics in game journalism' got you considered a misogynist neckbeard.
Didn't the FBI's study into GamerGate reveal that something like .4% of all the harassment was by people actually involved in it, and the vast majority was by unrelated trolls looking for lulz? There definitely was some harassment, which isn't a good thing, but the anti-GG people always downplayed exactly how much they were doing the same things as their opponents, while denying that there was anything like an organised anti-GG and also exaggerating to a greater or lesser extent some of their harassment.
My current understanding is that it was speds vs. speds with trolls and opportunists doing their best to inflame everything to make a glorious dumpster fire. And the people who profited the most from it were the figureheads who turned being oppressed from either side into a quite lucrative living.
