How does this matter anymore? OpenAI is the most known company from the last year. You don’t need specific person anymore to market about your company. If it is up to single person whether company is worth investment, then everyone just hopes that eventually OpenAI will turn to full-profit mode.
It is pretty clear, that if board wants to run company for greater good, for-profit-only CEO must leave.
Regardless of who they fired, if the board is known to make arbitrary and capricious decisions about top executives without so much as a heads up to large investors, it's not clear that any investor will see them as being worth investment.
