Not true in this instance. They implemented the Linux ABI, which means software can run on the linux subsystem without recompilation.

Cygwin allows running GNU software on Windows, but it doesn't implement the Linux ABI. Therefore Cygwin requires software recompilation.

The big advantage of WSL is that you can run native linux binaries.

#sigh# Clearly the joke was not funny if it had to be explained.

For decades, Richard Stallman has been calling it GNU/Linux, because the OS “aside from the kernel” was GNU, and Linux is the kernel. https://www.gnu.org/gnu/linux-and-gnu.en.html

Now, we have a Microsoft system that runs the Linux binaries, which are GNU according to Stallman, but not running them on the Linux kernel. You’re naming the entire system after the one component that is missing. By the same logic that normal Linux should be GNU/Linux, Linux containers on Windows should be GNU/Windows.
