Nobody is forcing him to keep doing this. He’s waking up every day and making the choice to keep running FB today the same way he ran it yesterday. He could just quit
This is a rebuttal to the “he’s in over his head” argument. If he personally is in over his head, the obvious solution is to quit and let someone more capable run the company.
I personally do not buy the “in over his head” argument, fwiw.
