You asked about the timeline. I kept my response limited to the timeline
You're right - I'm a goalpost-moving jerk, and I'm sorry.
From what I can tell, Depression Quest was released on the day of Williams' death. That's not taking advantage, that's an unhappy coincidence. I'm pretty sure release dates are set more than 24 hours in advance. Quinn had to option of pushing the release, but it's such a quagmire of morality, I can't bring myself to judge whether that would have been the right decision or not.
As for the "coverup", that's another item I just haven't seen evidence of. It felt entirely organic to me - a bunch of people saw a witch hunt and shut it down. It doesn't take a conspiracy for an idea to spread between reddit, gamasutra, kotaku, fark, 4chan, and wherever the hell else - these communities have plenty of overlap. The first idea to spread was the Quinnspiracy, and the second was that it was toxic, with moderators acting accordingly Now, I haven't seen the original threads (and I think at this point it would be a good idea for everyone involved to republish any of the original material), but from what I've seen in subsequent threads, I suspect "toxic" was a valid judgement.
