Everyone who's little-r rich claims to be middle/working class, and every private jet guy claims to have grown up middle/working class. I once had an expat from a poor country tell me average people back home have servants, which is mathematically impossible given servants are people too.
You see, they worked for and earned their money fair and square, unlike some other, slightly richer people. And then there's some that just straight up buy into "meritocracy", and think the African children are lazy.
Microsoft basically owns them. If anything they would be absorbed into Microsoft. The openAI brand is probably too valuable at this point to shelf it, they'll keep it as is. Just my guess.
They don't unless the board shakeup was bigger than I realise. OpenAI is a nonprofit, and could even shut down and destroy everything if they felt it advanced their mission. Microsoft could sue them, but would probably lose, because that's what the agreed to when they bought into the capped-profit subsidiary.
