That's fair. I don't mean that Windows should be replaced. I mean that Windows should do what Windows is good at.

Trying to introduce Linux into Windows isn't one of these things. Doing a UI refresh is fine but trying to make Windows UI conform to spatial computing isn't going to help it or the ecosystem in the long term.

If you look at their app building documentation, it's extremely disconcerting. This much compatibility overhead isn't helping the ecosystem grow.

BSD, IllumninOS, IBM z/OS did it first in supporting Linux APIs in some form, either by syscall remapping or VMs.

Linux compatibility has become more relevant than POSIX, and the easiest way to achieve it is just to bundle it for the ride.

In Microsoft's case, they want to cater to the market that buys Apple devices, to actually develop GNU/Linux software and couldn't care less about Apple's ecosystem, aren't happy with it, and don't bother to support Linux OEMs.

It seems to be working.

z/OS has only gained support for running Linux binaries quite recently, in z/OS 2.4 (released September 2019), which supports running z/Linux Docker containers (zCX). Prior to that, z/OS had no built-in support for running Linux binaries in any form. Microsoft released WSL1 in August 2016. So z/OS got this feature 3 years after Windows did.

You might be thinking of z/VM or PR/SM, both of which support running z/Linux virtual machines (but neither of which is z/OS); or of z/OS Unix System Services, which offers some degree of source compatibility with Linux (through its implementation of the UNIX 95 standard), but doesn't have any Linux binary compatibility.
