Okay, so overwhelmingly the participants in the Not That Awesome document found out the reality of all this about two weeks ago, so this is only slightly less fresh to them as it is to everyone else today. It was decided that it wasn't their story to tell, especially since the known victims at this point just want it to go away. The people who knew for longer had been specifically asked by the victims to say nothing. They didn't (don't) want to go through the intensity of that particular scrutiny, especially since it would spill over to much of the community and especially Justin's widow, creating a lot of traum, and for what? After all, Justin functionally settled the issue himself, and there's complicated issues specifically when it comes to managing the risk factor that is the GamerGate crowd.
They have, to no one's surprise, already started digging into every nook and cranny, digging out every ancient innuendo or accusation, and using it to try to identify victims/hurt people in general. I have little doubt that by the time I get home tonight I'll have between a dozen and two hundred essages accusing me of all sorts of stuff by simple proximity. The self-contradicting narratives are already starting to brew, looking for a witch to hunt.
We knew that the information would have gotten out eventually, and in a certain sense, needed to get out eventually, but ought to have come from the impacted individuals.
