Bought-out executives eventually join MS after their work is done or in this case, they get fired.
A variant of Embrace, Extend, Extinguish. Guess the OpenAI we knew, was going to die one way or another the moment they accepted MS's money.
The board as currently constituted isn't some random group of people - Altman was (or should have been) involved in the selection of the current members. To extent that they're making bad decisions, he has to bear some responsibility for letting things get to where they are now.
And of course this is all assuming that Altman is "right" in this conflict, and that the board had no reason to oust him. That seems entirely plausible, but I wouldn't take it for granted either. It's clear by this flex that he holds great sway at MS and with OpenAI employees, but do they all know the full story either? I wouldn't count on it.
