Perhaps they turn hostile because of macOS users. Such users have submitted sloppy this-works-for-me-style build patches to my project, which later were deemed incorrect by actual macOS experts. I had to do everything over again.
Then I was rudely accused of not using cmake, when autotools perfectly support cross builds (better than cmake on Linux).
It is not my problem if a purported Unix does not ship gcc or if clang cross builds are painful. Go and install gcc!
If Apple were interested in being supported, they'd fix their tool chain and provide free testing infrastructure to OSS developers.
