Regardless, Microsoft is free to do what they want, including licensing parts of a software as open source while keeping other things closed source, but their loud marketing around .NET being fully open source has caused other projects (like Godot) to move from Mono to .NET. If .NET turns out to not be open source in practice because you can't compile it for Windows without proprietary stuff, then that will be damaging to the projects using .NET for open source development. Here's to hoping that I just horribly misunderstood everything and this is not the case.
