I'm not making that comparison (I never mention macOS at all); not sure where your reading that. I'm merely pointing out that a response of "it works for me and has for 10+ years" when someone says "it doesn't work on my laptop" is entirely unhelpful.

In fact it shows that they don't at all get the point you've made that Linux runs on orders of magnitude more hardware variants than macOS does and thus it should be obvious that all hardware can't be equally well supported.
