Apple spent countless development hours writing an entire BootPolicy framework to allow other OSes (and self-built macOS kernels) to run on these machines. Not only that, their secureboot implementation implements per-OS security modes, which means you can dual boot Linux with a full secure macOS, including running iOS apps and Netflix in 4K. Can't do that with LineageOS!
Linux on M1 Macs is "supported" exactly the same as Linux on any random PC without manufacturer support. Sure, it's more work to get running, because it's a new undocumented platform... but we've signed up to do the work. If Linux on these machines is an "unsupported hack" then so is Linux on the vast majority of desktop/laptop computers people use.
