He had a weird exit from Y Combinator too, I don’t doubt this at all.

But in those days with the company on the line with everyone trying to dig in to why he got fired, nobody leaked this? Nobody had a good example of something he did which was not acceptable behavior for a CEO?

I just can’t see it being a big enough deal to fire him over so abruptly, without even telling Microsoft ahead of time, if nobody has the killshot example of him doing something crazy. Maybe he’s just an asshole. There are lots of asshole CEOs.
