Funnily, I think all the non-profit motivated talent has left, and the people left behind are those who stand to (and want to) make a killing when OpenAI becomes a for-profit. And that talent is in the majority - nothing else would explain the show of support for Altman when he was kicked out.
I read at the time that there was massive coordinated pressure on the rank and file from the upper levels of the company. When you combine that with OpenAI clawing back vested equity even from people who voluntarily leave, the 95% support means nothing at all.
