Hot take: CPython is not an important project for Microsoft, and it is not lead by them. The faster CPython project had questionable acheivement on top of that.
Half of Microsoft (especially server-side) still runs on dotnet. And there are no real contributors outside of microsoft. So it is a vital project.
They also laid off one of the veteran TypeScript developers. TypeScript is definitely an important project for Microsoft, and a lot of code there is written in it.
