My guess -- Microsoft wasn’t excited about the company structure - the for-profit portion subject to the non-profit mission. Microsoft/Altman structured the deal with OpenAI in a way that cements their access regardless of the non-profit’s wishes. Altman may not have shared those details with the board and they freaked out and fired him. They didn’t disclose to Microsoft ahead of time because they were part of the problem.
