With antitrust regulators (including, to a certain extent, the relatively feckless ones in the USA) breathing down Apple and Google's necks, they might not be able to get away with enforcing that rule for long.
In contrast to MacOS, I can run Windows on pretty much every x86 machine available. Thanks to EU reseller laws, I can also obtain a cheap license. Finally, I have to pay a small one-time fee for a developer account at Microsoft, in contrast to the recurring fee Apple is charging.
So… that's apples and oranges to me.
By the way, try to install Windows ARM, or Windows CoPilot+ PC on any board you feel like.
