But then the .NET team shouldn't be asking every now and then on social media, why other languages get chosen, outside the Windows ecosytem.

That's not how open source works / should work though. If the Go maintainers (that happen to work at Go) ignore problems that the MS teams flag up, they can fork the language.

MS literally already has a whole team around Go. And if they didn't, Go is completely open source.

C# is open-source in name only.

I know a few teams in Azure Networking teams that use Go. I don't think it's uncommon.
