The Windows Subsystem for Linux is now open source

Today we’re very excited to announce the open-source release of the Windows Subsystem for Linux. This is the result of a multiyear effort to prepare for this, and a great closure to the first ever issue raised on the Microsoft/WSL repo:
I still will never understand why it's not called Linux Subsystem for Windows.
There's a trademark for Linux so Microsoft can't name a product starting with Linux.

So they can use Linux in the name, just not at the beginning? We're so stupid. Can they do Windows Subsystem for Coke? Or Windows Subsystem for McDonald's? Or Windows Subsystem for MacOs?
Good gravy.
Still doesnt explain why it wasn't called Windows Linux Subsystem (WLS)
Not in the spirit of free software, if you ask me.
I got hung up on this before too but it's apparently "Windows Subsystem for (using) Linux"
I think it is because Windows has many subsystems, it's just that you don't hear about most of them aside from WSL.
So it is referring to the particular Windows Subsystem (of which there are many) that can run or emulate Linux.
Wait, Windows still has POSIX subsystem or is it only listed for documentation reasons (it was there at least in old NT days)?
Maybe they just named it like the previous attempt: https://en.wikipedia.org/wiki/Windows_Services_for_UNIX
