First of all, ARM is not owned by Apple, and if it weren’t so open, so open source friendly, Apple would not have been able to create Apple Silicon chips in the first place.
Secondly, lol, Asahi Linux proved that, not only could apple’s apple silicon chips be reversed engineered, but that it was both a worthwhile enterprise and that Apple wouldn’t come after them. Because Apple officially stated that they just do not care. Apple intentionally designed the chips to be capable of booting and running alternate operating systems. They, themselves, created a very clear and open development pathway.
Oh, not to mention that it is definitely Linux.
So… That’s what the fuck I’m talking about. Again, what the fuck are you talking about?
