Maybe one of the reasons, but not clear to me it's the main or only one. Another potential reason is that he was attempting to individually manipulate board members into trying to support him in getting board member Helen Toner fired. There's also the rumor of the Q* advance which the board apparently heard of via some concerned employee(s), not from Altman.

Maybe there was some final straw that got the board to act, but could have been accumulated grievances about Altman not being candid with them.

All of those other things are supporting considerations, but none of those alone would be enough to have triggered this drama.

However gross self-dealing is generally a for-cause grounds for termination everywhere. If the employees hadn't bought into the cult, we'd be grouping Altman in with Neumann and the other charlatans.
