If OpenAI hadn't restructured they wouldn't have gotten any money from Microsoft and they would have either run out of money or the team would have left and started ClosedAI. There's no scenario where they developed GPT-3/4 while staying nonprofit.
I'm guessing that's the point. Ethics required getting out of the 501(c)(3), so the ClosedAI thing sounds more ethical. The 501(c)(3) should've collapsed or not exist.
BS, you can still make a deal with microsoft as a non profit, where the deal gives them an exclusive licence to use the result in exchange for financing.
MS doesn't care about how money it cost, they care about the fact it's their ticket back into the fight with google and apple.
Hard to believe. Nobody is going around throwing billions without any hope of recouping any of it eventually (except the EU of course but giving any money to organizations which actually might be capable of building something useful is against their policy).
