> 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.
