OK, so this seems like a list of gripes about MacOS.

It's absolutely fine to have personal preferences on UX, customisability etc. This is why I swore off GNOME at the Gnome 3 transition and have never looked back, for example. If it doesn't work for you it doesn't work for you.

But it doesn't really support the assertion that you can't use the power of an M1 because of "how locked down everything is and most of that power is pretty useless".

Again, not trying to say "Thou shalt love MacOS!", but more that I don't think your points there really reflect something so locked down as to be useless. Just something with a UI you don't get along with.
