Because he is possibly the most desireable AI researcher on planet earth. Full stop.
Also all these cats arn't petty. They are friends. I'm sure Ilya feels terrible. Satya is a pro... Won't be hard feelings.
The guy threw in with the board... He's not from startup land. His last gig was Google. He's way over his head relative to someone like Altman who was in this world the moment out of college diapers.
Poor Ilya... It's awful to build something and then accidentally destroy it. Hopefully it works out for him. I'm fairly certain he and Altman and Brockman have already reconciled during the board negotiations... Obviously Ilya realized in the span of 48hrs that he'd made a huge mistake.

There are lots of people doing excellent research on the market right now, especially with the epic brain drain being experienced by Google. And remember that OpenAI neither invented transformers nor switch transformers (which is what GPT4 is rumoured to be).
But what does Ilya regret, and how does that counter the argument that Microsoft would likely be disinclined to take him on?
If what he regrets is realizing the divergence between the direction Sam was taking the firm and the safety orientation nominally central to the mission of the OpenAI nonprofit and which is one of Ilya's public core concerns too late, and taking action aimed at stopping it than instead exacerbated the problem by just putting Microsoft in a position to take poach key staff and drive full force in the same direction OpenAI Global LLC had been under Sam but without any control fromm the OpenAI board, well, that's not a regret that makes him more attractive to Microsoft, either based on his likely intentions or his judgement.
And any regret more aligned with Microsoft's interests as far as intentions is probably even a stronger negative signal on judgement.
