Unfortunately, I'm pretty sure if Apple did provide documentation, people would complain that it's incomplete, or would complain when it changes. I'd love a world where all tech documentation is open, but there are competitors etc etc.

Apple is a remarkably focused company with a lot of experiments that never see the light of day. They don't sell their chips or motherboards to anyone else.

Qualcomm/Broadcom etc exist to make their chips for other companies to use and still getting real documentation from them is often not possible unless you are a giant OEM, commit to millions in orders and sign lots of NDAs.

Apple's not only created a pretty great integrated CPU/GPU and nearly seamlessly transitioned CPU platforms (AGAIN!) but they are at the very beginning of this roadmap.

I'd LOVE them to empower/support Linux on Apple Silicon (as they seem to be saying they will for Microsoft) but I expect a generation of two of chips before things solidify/stabilize enough for them to open up the platform.

And, it's not like this is something within their business model or is going to give much value back to them.

Lots of people say Apple "Needs" to do whatever... Clearly they don't as they seem to be surviving OK doing things how they want.
