Turning it into an emergency and surprise coup with innuendo of wrongdoing looks to have been a huge mistake, and may result in total loss of control where a more measured course correction could have succeeded.
Looks like they were right to boot him, but may have done it way too late, having already de facto lost control due to the direction he’d guided the organization. If he comes out on top, it’ll mean the original OpenAI and its mission is dead, looks like to me, and the board was already cut out months ago but didn’t realize it yet.
