Here is a different perspective. Theoretically, the board is supposed to work like this, and exactly has a purpose - to vote on very important matters.
Given what proof they had on the table. Greg Brockman, Ilya Sutskever, and independents such as Adam D’Angelo, Tasha McCauley, and Helen Toner could drive 3+ votes against Sam Altman.
Rarely do we see board in action. And we saw this one today.
