Apple doesn't actively lock and act hostile towards the reverse engineering folks. They just do their thing and sometimes do small jests to allow these folks to boot anything they want and play with the hardware.
...and while they're standing away from GPL stuff, they do have a dedicated site for Open Source software: https://opensource.apple.com/
Go to releases, and see what they do there.
if you are in the business of buying parts, assembling them, and selling the assembly under your brand (as tuxedo and others like them are), then Apple is a indeed not an option. Their chips might be the best, but you still can only get them in Apple devices, in the specs Apple provides and with no official support for any OS beside macOS / iOS.
