> Apple, which exclusively produces for their own lineup, and has inarguably the best-performing chips by far in raw performance and power efficiency to a tune

  At least the incentive for highly skilled reverse engineers is there and it's showing in pretty solid support [2] and contributions. For example Apple is known for re-using SoC blocks across many generations - according to an (admittedly unsourced, but I've seen it stated multiple times) HN comment [1], the UART has been the same since the first iPhone through all the years past including M1/M2 machines, whereas Samsung alone has four incompatible variations, and all the other vendors each have their own idea as well, while the entirety of x86 can be spoken to in bare-metal assembler.
