Intel refuse to document significant portions of their technology, and Linux works less well on their platforms as a result. They definitely do a better job of documenting things than Apple, but I'd really frame this as a difference in degree rather than in kind.

Can you give some examples - I thought Intel was pretty involved with the Linux foundation and have released a lot of open source code?

They release plenty of open code, but then you also end up with situations like them not documenting DPTF and so laptops running slower under Linux than under Windows (https://mjg59.dreamwidth.org/54923.html has more on this), failing to document the requirements for entering deep power saving states and so laptops consuming more power under Linux than under Windows (https://mjg59.dreamwidth.org/41713.html), not doing any upstream work on the IPU4 camera platform so the webcam doesn't work on various laptops - instead this ends up with random people outside Intel having to reverse engineer stuff or do integration work on Intel's behalf. Is it better than Apple? Yeah. Is it good? No.

Intel encrypts their microcode, for example.
