Most of the article is well-trodden ground if you've been following OpenAI at all, but I thought this part was noteworthy:

Some members of the OpenAI board had found Altman an unnervingly slippery operator. For example, earlier this fall he’d confronted one member, Helen Toner, a director at the Center for Security and Emerging Technology, at Georgetown University, for co-writing a paper that seemingly criticized OpenAI for “stoking the flames of AI hype.” Toner had defended herself (though she later apologized to the board for not anticipating how the paper might be perceived). Altman began approaching other board members, individually, about replacing her. When these members compared notes about the conversations, some felt that Altman had misrepresented them as supporting Toner’s removal. “He’d play them off against each other by lying about what other people thought,” the person familiar with the board’s discussions told me. “Things like that had been happening for years."
