As others have noted, the "Reduce Motion" doesn't fix anything (neither does Reduce Transparency).

These terminal commands don't fix the problem- there are still lengthy animations, e.g. when swapping desktops or opening folders. These are tasks I sometimes do multiple times per second on Linux.

You're missing the point here. The "old" Apple would never have tolerated a janky feature that inverts responsibility onto the user and behaves poorly out-of-the-box. Back then it was either lightning fast, jank-free, and intuitive -- or else it doesn't ship.

But this eroded over time. Nowadays both Mac and iOS are bloated pieces of crap that reek of design by committee. A lot of people blame Alan Dye (and they are probably right to do so) but there are other factors too. With Steve and Jony gone, they need someone who cares to step in and assert control once more

Hilariously, this is what the Gnome 2 people would have called an "Unbreak Me" option, something they tried culturally to eliminate more than a decade and a half ago. With... not total success, I guess, but the resulting environment tends to have a very high level of "work and not suck by default" quality -- something that steadily evolving commercial software tends to struggle with maintaining.
