> Apple explicitly chose to provide a way to boot third-party operating systems

And they explicitly chose against a UEFI interface like prior Macs, which would have actually enabled proper Linux support. Now you have poor people trying to reverse-engineer a Devicetree from scratch to get basic features to kinda work, emulating hardware features in software and working with no documentation from Apple. They "explicitly" chose to expose iBoot because otherwise you wouldn't be able to reinstall MacOS in a full data loss situation.

By comparison - reverse engineering an unsupported AMD or Intel CPU would at least give you some basis to work off of. You have UEFI as standard, ACPI tables provided by hardware, even CPU documentation and Open Source drivers to work off of most the time. Asahi shot themselves in the foot by trying to support hardware that doesn't support them back. You can argue that Apple was conspiring to help, but we have no actual evidence of that.

> Their SoC stuff dates in some components AFAIK back to the very first iPod SoCs in its design.

And none of those platforms ever got proper Linux support either. I love Linux as much as the next nerd, but it doesn't seem wild to suggest that Apple Silicon will never have feature-complete Linux support. And for many people, maybe that's okay!
