According to the letter they consistently refused to go on the record why they did it and that would be as good a reason as any so then they should make it public.
I'm leaning towards there not being a good reason that doesn't expose the board to immediate liability. And that's why they're keeping mum.
That might also explain why they don’t back down and reinstate him. If they double down with this and it goes to court, they can argue that they were legitimately acting in what they thought was openAI’s best interests. Even if their reasoning looks stupid, they would still have plausible deniability in terms of a difference of opinion/philosophical approach on how to handle AI, etc. But if they reinstate him it’s basically an admission that they didn’t know what they were doing in the first place and were incompetent. Part of the negotiations for reinstating him involved a demand from Sam that they release a statement absolving him of any criminal wrongdoing, etc., And they refused because that would expose them to liability too.
Unfortunately lawyers almost always tell you to be quiet, even when you should be talking. So in this case listening to legal advice might have screwed them over, ultimately.
Yes, that's a possibility. But: Sam may not be the only party that has standing and Sam can only negotiate for his own damage and board liability, not for other parties.
I'm leaning toward the reason being that Sam did something that created a massive legal risk to the company, and that giving more details would cause the risk to materialize.
