So far I like best that he was probably fired for not being enough of an AI doomer, i.e. deprioritizing AI safety and diverting too many resources from research to product service, all the while only paying lip service to the ea/rationalist orthodoxy about heading off the impending birth of AI Cthulhu.
Any remaining weirdness can be explained away by the OpenAI board being sheltered oddballs who honestly though they could boot the CEO and face of the company on a dime and without repercussions, in order to bring in an ideologically purer replacement.
'We are the sole custodians of this godlike technology that we can barely control but that we will let you access for a fee' has been a mainstay of OpenAI marketing as long as Altman has been CEO, it's really no surprise this was 'leaked' as soon as he was back in charge.
