I can see the argument when it comes to locked-down mobile devices, but macOS is a general-purpose operating system with no restrictions on software sources that can't be easily disabled. Nearly every program available for Linux (excepting OS-specific stuff like desktop environments) is available for macOS, commercial and free, and there's plenty more that's macOS-only. Asahi is cool, but it's mostly used by enthusiasts - there's very little practical use for it as a macOS alternative. I think that you'd have a hard time convincing regulators that this cause really matters.

In any case, though, Apple agrees with you, and they explicitly built support for non-macOS OSes into the bootloader. This is a bug in the first developer beta of a new release.
