It looks like Microsoft's ambitions to completely cannibalize OpenAI is coming to pass. Apparently, Microsoft already has a perpetual license to all of OpenAI's IP (link), and owned all the physical hardware running the OpenAI GPTs. So now that they're about to acquire basically OpenAI's entire staff OpenAI literally has nothing.
I think the interesting angle is the anti-trust angle. The board's ouster of Altman has essentially allowed Microsoft to strip OpenAI for parts without having to compensate the other investors or receive anti-trust scrutiny. It is a massive win for MS.
I can't imagine being so brain poisoned that you'd quit your job just cuz your shitty tech bro boss got fired.
Since OpenAI is a kayfabe "public benefit" company, it sounds like the board actually decided to stand up for the company's chartered values, which are essentially the creation of a AI god to solve all humanities problems. If you're a tech worker just trying to make bank, it's not a hard decision to side with the people who want to make money versus the people who actually believe that bullshit.
Also changing jobs is usually a good idea in tech anyways. If they were bluntly offered so many positions like that, they probably got a little bit of a raise as motivation.
