Right. The board of directors at open ai were unhappy with how the ceo was communicating with them, so they voted him off.

Then a group of stakeholders and staff were like “no guys, we want him back or we resign/withdraw our funding”

So now he is back with Microsofts blessing, MS being their largest stakeholder, and it sounds like some of the directors who voted to out have also been booted.

Here is a decent writeup.
