The big question in my mind is the reported threat from MSFT to withhold cloud credits (i.e. the actual currency of their $10B investment). Is this true? And are they going to follow through?

I don't buy for a second that enough employees will walk to sink the company (though it could be very be disruptive). But for OpenAI, losing a big chunk of their compute could mean they are unable to support their userbase and that could permanently damage their market position.
