I would seem OpenAI now have very little autonomy as a company. Since any IP they currently have can be taken by Microsoft there's very little incentive for other companies to invest. And since OpenAI isn't profitable they are now 100% dependent on Microsoft to continue operating.
I think we may as well consider OpenAI a Microsoft acquisition since this appears to more accurately describe the relationship here.
Perhaps Sam Altman was just too stupid to understand this, but I suspect that isn't the case. It seems he probably knew OpenAI would effectively become a Microsoft research project as part of their deal, and therefore we should probably assume that they will operate with for-profit incentives – and with those of Microsoft's more specifically.
I guess what I'm saying is that this doesn't surprise me, and I'd expect more of this to come.
