> people that are unreasonably attached to this standard and try to use it everywhere without being level-headed about its usefulness This is certainly a better way to put it! But it's possible that they indeed mostly had the POSIX standard in mind when trying to create their software, possibly because that's what they were developing on (e.g. one of the *nix distros or something compatible) and that's what was available easily. Support for Windows might have been a bit of an afterthought, or something that was added later. It's still better than nothing, even if not always viable.
