Microsoft was reportedly unaware of OpenAI's decision to oust CEO Sam Altman until just before the news was made public. This development has sparked discussion about the relationship between Microsoft and OpenAI, as well as the structure of OpenAI as a non-profit with a for-profit subsidiary. The situation raises questions about the motivations behind Altman's ouster and the implications for OpenAI's future. Microsoft's investment in OpenAI and their exclusive access to its technology are also being reexamined in light of these events.
