This is not a rumor. The article references a tweet made by Satya Nadella itself. It is an official announcement. The board drama no longer matters here.
By the way, $900k comp with illiquid OpenAI shares means nothing anymore when Microsoft can now hire them with $900k+ in fully LIQUID compensation.
Not only that, OpenAI employees can go join Microsoft to work under Sam and Greg, who many of them seem to support.
This is a pretty big win for Microsoft.
