It's all very ambiguous, but if he had been there for the board meeting where he was removed, I imagine he would have quit then and it would have been in the official announcement. It comes across like he didn't quit until after the announcement had already been made.

It is:
> As a part of this transition, Greg Brockman will be stepping down as chairman of the board and will remain in his role at the company, reporting to the CEO.
