Isn't that also true for pretty much every computer except Apple's?

If the pc components happen to be compatible (current or previously used components in Apple hardware), it's possible to install OSX/macOS on it, hackintosh style[1].

I've never had a good experience trying to install Linux on a Mac. Maybe it's better these days.

Unless something has changed, it's annoying as hell to actually install Linux or Windows over the entire hard drive. They want some specific bits at the front of the hard drive.

That's thanks to Windows and Linux being designed for portability, rather than any engineering feat by Apple.
