Curl runs on at least 89 operating systems[0]. Apparently 88 of them are then better at "being Linux" than Windows.

How many of them are supported in mainline Curl, aren't POSIX and aren't dead operating systems?
What is a dead operating system anyway, and how is that relevant to the point that Windows is the hardest OS to maintain support for?
* See for instance the config-*.h files in https://github.com/curl/curl/tree/1c567f797bce0befce109bceac...
No longer maintained / barely changing, like MS-DOS, Mac OS 9, Amiga OS (which does occasionally get an update but usually not much in the way of core changes)
It's relevant because Windows is a moving target and the dead operating systems aren't so there's not a lot of support work needed for them nor will there be as much of a user base.
Mac OS 9
DR DOS
OS/2
VMS
Windows CE
z/OS
MorphOS
Atari FreeMiNT
OS/400

Actually probably a fourth (EDIT: after looking more closely, make that ~half) or so of the list are not in any way UNIX.
I see Windows, Windows CE, XBox and even MS-DOS on that list.
Edit: And there are at least 4 Windows flavours in the list!
There are probably more there. I recognize about half of those names only.
Are you really saying that it's normal to be harder to port some software into Windows than into z/OS?
No, I'm saying that from 89 OSes mentioned on that picture, a lot of them are better at being *nix because they are *nix.
But answering your question, sure! The only good thing in POSIX is that you have easy access to a lot of *nix software. Other than that, POSIX is a spectacularly bad API.
Windows doesn't really care about running *nix software natively, because most of Windows userbase just want and use different things. Therefore, why invest into a bad API? For those wanting to use *nix software on Windows, there is Cygwin or WSL anyway.
