C# is open and alternative implementations like Mono exist.

Mono is just a side project of Microsoft. A commoditized alternative to Microsoft's toolchain.

Miguel was conned into believing that it'll be completely independent like OpenJDK, but it didn't turn out like that.

IOW, C# is as open as VSCode.

OpenJDK is a side project of Oracle, too.

Not really. Plus, Red Hat Software, MS, Apple, Amazon, IBM, SAP are all developers for OpenJDK, as well as contributions from other major firms.
