Nobody comes out of this one smelling clean. And everyone suffers for it.
Kotaku suffers a double-punch, once for losing even more credibility than Game Journalism's lost in general in the last few years, and somehow, impossibly, making the entire situation worse than it's ever been. Most of us didn't even realize this was possible before this afternoon. This is like Tupacalypse-level fail. It's 100 proof, and thus illegal in some states.
Quinn suffers in that she herself has no credibility thanks to this, has come across as an inveterate liar and a shithead, one willing to cause gigantic firestorms across multiple communities and outright lie if it suits her. Any cause she's been attached to (and there's some legitimate ones under the stupid) automatically suffers just due to her being associated with them at some point.
Wizardchan suffers because even though the overpowering majority of them had absolutely nothing to do with this, they're getting blamed because of the actions of a few retards - which again, is analogous to what happened with /pol/ provoking the infamous tumblr raid. The majority of the Wizards wanted none of this shit (something patently obvious from even a cursory look at their site), and were perfectly content to be left alone before this nonsense occurred. Now, they get scrutinized and hateboxed like they masterminded the whole thing, when any objective analysis shows that they very likely got used.
The CWCki suffers because, like Wizardchan, had some irate cock-hydrant decide to scapegoat it, and drag all of it, likewise, through the mud as some sort of mastermind, when, again, it's highly evident to even casual onlookers that this is a load of shit.
So what we have here, to repeat what I said earlier, is a very obvious case of Kotaku being exposed for an act of fuckery (quite literally), Zoe Quinn being further proved a serial asshole who has single-handedly undermined everything she has ever been associated with, Wizardchan being listed as some kind of trolling superpower when it would prefer to be left in its own little corner of the internet to play trucks, and the CWCki, as ever, is left to pick up the pieces. What we know for sure is that Quinn's the one who started this, and that someone targetted both the Wizards and CWCki clearly in an effort to play them off one another.
