Altman has always been a bit sly, I am not surprised if he has made some backroom deals that don't sit well with the board. But there is a fine line between doing the right thing and unable to do anything at all. Sometimes, it is better to have the moderately bad guy that can at least bring progress instead of a virtuous leader that can't win a fight.
I guess only time will tell. Right now though, OAI is not looking good and depend on how Microsoft was involved in all of this, someone's seat might get a bit shaky.
