There were way more people who framed the board, than Altman as someone who did bad. At least until Monday. There were a ton of hearsay why ousting Altman is bad, without any context and internal info. And many of them was written by PR people. For example, "the last time when this happened was with Steve Jobs 1985". This is clearly a statement which wants you to direct towards that Altman is the victim. When it's not even true, because it happens all the time, like with Emmanuel Faber at Danone.

Btw, this is the most probable reason right now: https://www.nytimes.com/2023/11/21/technology/openai-altman-...

It's also par for the course in these scenarios for the public story to be completely fabricated and have nothing to do with whatever thing actually pissed off the board, so we may never know what really happened
