I agree but the *nix part became less and less significant. Bundled Unix tools are ancient. Compiling your own kernel is almost an anathema (it is possible but you will have nonstop hurdles, you will lose a lot of features and you will have to fight the security system too many times to remain sane).

Even the UI conventions that let you use the keyboard instead of the mouse are now often broken by Apple itself (it impacts power users more than impaired people since accessibility features are still good).

And no containers - those require you to run a different kernel on a VM.

Frankly I feel that macOS went back to being like Mac OS 9 in a lot of aspects - it's just enormously bigger and has a proper foundation but the UI is again mouse centric and proprietary and the system is more tightly coupled than ever with the hardware
