And in regards to OpenAI, note that (according to TFA), Microsoft has barely distributed any of their committed "$10 billion" of investment. So they have real leverage when threatening to deploy their team of lawyers to quibble over the partnership contract. And I don't think that "undermines confidence" in Microsoft's contractual agreements, given that there are only two or three other companies that have ever partnered with Microsoft at this scale (Apple and Google come to mind).
