Notably, Sam/Greg do not guess or insinuate why he did a coup.
I think the Reddit user is legitimate.
Im not saying that real leaks dont happen, but that pre-running the news is really weak evidence the on reddit, unless the claims are incredibly specific.
I dont think there was anything they said on reddit that was very specific, and several posters in the HN thread speculating the same thing, just without claiming to be "in the room".
It is kind of like publishing multiple weather predictions, and then claiming credit for the one that is correct.
Thats the point, it doesnt matter if they do or dont.
If you read through their post history, they have a comment or sentence for almost every possible reason:
Difference in vision
forcing development to fast
Didn't listen to safety concerns
Lying about finances
Making deals without the board
Hiding financial matters.
It is like someone is rattling off the top 10 guesses for the reason from HN or predication markets.
Now if they said something like Ilya Sutskever called Sam at 1215 on hangouts to tell him, That would be a be pretty solid proof.
