IANAL
And the other individuals aren't even quoted, which is strong evidence that they didn't actually say anything even remotely in support of "reaffirming" the nonprofit structure (especially given that his lawyers were heavy handed with including quotes when they could be even remotely construed in favor of Musk's position) and that Musk is unilaterally characterizing whatever they actually said to support his claims, however reasonable or unreasonable that may be.
Due to the money at stake, and given that both Musk and Altman have serious credibility issues that would make a trial outcome impossible to predict, I expect this to be settled by giving Musk a bunch of stock in the for-profit entity to make shut up.
