When OpenAI went in with MSFT it was like they have ignored the 40 years of history of what MSFT has been doing to smaller technology partners. What happened to OpenAI pretty much fits that pattern of a smaller company who developed great tech and was raided by MSFT for that tech (the specific actions of specific persons aren't really important - the main factor is MSFT's gravitational force of a black hole, and it was just a matter of time before its destructive power manifests itself like in this case where it just tore apart the OpenAI with tidal forces)
