That's not really because Apple hates allowing you to install Windows, but rather because you can't actually acquire a Windows for ARM license. Once again, Apple has stated that Bootcamp for Apple Silicon is "up to Microsoft". And ARM Macs are still just a minority of the computers that Apple sells. The rest have Bootcamp, which allows you to just turn your Mac into a Windows machine.
Saying that "Apple will never allow you to replace macOS" is just plain wrong when they've been allowing you to do that for the past 14 years.
You might as well argue how Bootcamp doesn't run on iPads.

You'd still have to develop all the device drivers required for this custom SoC. After all, Linux doesn't need a license but without extensive documentation and support from Apple it's like saying you're free to challenge your boss openly, it's pedantically true, but it is impossibly impractical for most.
Unless Apple provides extensible documentation for 3rd party drivers to be developed for their SoCs it's just cheap talk from their side.

This isn't much of a "gotcha" - I do think it's outrageous that Apple gets away with selling these gimped iOS devices that only run Apple-approved software.
Would consumers stand for this with any other devices? A stapler where you had to buy staples from the manufacturer? A car that only drives on manufacturer-approved roads? A dishwasher that will only wash approved plates?
