Okay, so since that was dis-proven, the main points of contention seem to be an alleged affair that Quinn had with a judge, censorship issues with 4chan, and death threats. And a bomb threat! I'm not sure about the donations, because it's not clear in the article you linked to who the benefactor was, and if there was anything wrong with that. What I don't understand so far is why people on the GamerGate side aren't distancing themselves from the people who made threats against Anita Sarkeesian. From reading this topic, they're saying the threats didn't happen. I would say "The threats happened, but it has nothing to do with our cause." There's a couple of bad apples in every group of people, but don't dismiss what they did.
Another part of this story that's fascinating is the subject of gamer culture, and whether video games are a form of art or entertainment. Then there's the way women are portrayed in video games. These came about from the youtube videos I think? But these subjects are too buried under all the mud slinging to have a discussion about them at this point. Kinda sad.
(Ah, I wasn't reading closely enough. Ben Kuchera who wrote a positive review of her game made a donation. I guess people count on impartial reviews, for an unbiased opinion. It's understandable why somebody would be a little irked but I still can't wrap my mind around how this became such a big deal. Maybe the indie game scene is bigger than I thought it was.)
