Greg and Sam were the creator of this current non profit structure. And when similar thing happened before with Elon offering to buy the company, Sam declined. And that was when where for OpenAI getting funding on their terms were much harder than it is now, whereas now they could much more easily dictate terms to investors.
Not saying he couldn't change now but at least this is enough for him to give clear benefit of doubt unless board accuses him.
The reason I don’t think the board fired him for those reasons is because the board has not said so! We finally have a semi reliable source on what their grievances were, and apparently it has nothing to do with that.
It’s weird how many people try to guess why they did what they did without paying any attention to what they actually say and don’t say.
Why do you think that? It still strikes me as the most plausible explanation.
