The other two board members have nothing in their history to suggest they have the stomach or experience exercising agency to be a significant part of this resistance. But they might be pretty inclined to make a useful ideological stand.
I’ll reiterate a point I and others have made: the person most hurt by recent OpenAI events is D’Angelo. All he has to do is make the valid point that OpenAI’s charter is to make AI available to all and twist it a bit to his extreme personal advantage. The difference is that most people seasoned in corporate warfare can see he is not acting out of altruism but to his personal advantage, and apparently the other board members cannot.
Inversely to the other board members not having a history of individual stands, D’Angelo does, and he also lacks indications in his work history that he is concerned with altruistic actions in general.
