From what I heard at the time, Elon was running OpenAI as, to some degree an element of the Elon keritsu. Neurallink was upstairs from OpenAI, and OpenAI badges would open doors at Tesla and vice-versa. Elon will also move people from one of his companies to another if the need arises. I think some of the OpenAI execs were very upset when he moved Karpathy from OpenAI to Tesla to take over Autopilot.
