Most high-risk investments still come with an understanding that the recipient will have a duty to the investor, making decisions that they believe in good-faith will lead to a return on that investment on some time-frame.
This one is very much an explicit, "You're giving us a donation. Don't expect a return." It's in an impossible-to-miss pink box. They can't be more clear about this.
If investors are concerned about those things, then they should not give money to people who pointedly leave those things on the table. Like this one:
> The Nonprofit’s principal beneficiary is humanity, not OpenAI investors.
Also, Microsoft got something for their money already. They have an independent license to the tech they can run themselves and iterate on.
The OpenAI board has no duty to Microsoft to get their input. MS might have believed their investment amounted to de facto control, but they're wrong.
