They were, at no time, under any obligation to do anything except what they wanted and no one could force them otherwise. They held all the cards. The tech media instead ran with gossip supplied by VCs and printed that as news. They were all going to resign 8 hours after their decision. Really? Mass resignations were coming. Really? OpenAI is a 700 people company, 3 people have resigned in solidarity with Altman and Brockman at the time.
Sam had no leverage. Microsoft and other investors had little leverage. Reading the news you’d think otherwise.
