Is .NET 5.0 and C# 9 a "threat" to D?

I fail to parse that question. I'm afraid. Do you mean to ask 
whether .NET users are porting the runtime to other operating 
systems themselves?

Most of .NET is licensed under MIT. It is my understanding that 
the entirety of the cross-platform code is released under that 
license. I do not know whether the Windows Desktop version of the 
runtime includes extra components that are still proprietary.

Not yet. There's a toolchain in the making that has been 
demonstrated to compile small C# programs down to standalone 
executables with size less than 1MB. Going from there to bare 
metal should be quite doable, but footprint would very likely 
still be an issue. Unfortunately, I don't have a link to the 
source anymore.

I think most of that work is supposed to be formally released in 
.NET 6.0.
