alt Hacker NewsM series macs are weird tho, yes the bootloader allows it but absolutely no documentation on the hardware, drivers etc. Can't help but to think the goal of this wasn't to actually allow third-party OSes, but for development purposes(and ye they could hide the feature behind apple account with paid dev license) or anti-anti-trust measures à-la Google with Firefox: in front of a jury of normal people they can simply say "look there's these nerds making Asahi" the same way "look we're not a monopoly Firefox has .2% market share".

The design of the exposed mechanism is explicitly about booting unsigned versions of MacOS. There is zero support for booting anything else, but no enforcement that it must be MacOS.
However, apple's justification for exposing this mechanism to users appears to explicitly include "booting linux" even if the mechanism has zero explicit support for booting linux.
I think they are wary about macOS becoming a designated DMA gatekeeper, it would certainly be very close to the user and income thresholds.

More weird than the opaque Management Engines on Intel or AMD chips that can take full control of your system at any time that you have no control over?

Apple has explicitly stated that allowing third party OSes is exactly the purpose of the new bootloader.
