As an aside: that letter contains one very interesting tidbit: the board has consistently refused to go on the record as to why they fired Altman, and that alone is a very large red flag about their conduct post firing Altman. Because if they have a valid reason they should simply state it and move on. But if there is no valid reason it's clear why they can't state it and if there is a valid reason that they are not comfortable sharing then they are idiots because all of the events so far trump any such concern.

The other stand-out is the bit about destroying the company being in line with the mission: that's the biggest nonsense I've ever heard and I have a hard time thinking of a scenario where this would be a justified response that could start with firing the CEO.
