In general when I install Linux on an Apple device I just assume there isn’t the same level of performance. I remember installing mint on a 2016 intel MBpro and the limitations/cons didn’t surprise me at all because I just kind of expected it to perform at 70% of what I expected from macOS but with far more free freedom/control. It ran very smoothly but you definitely lose a lot of functionality.
That's very cute, but it's not why Apple laptops run Linux poorly.
Apple Silicon has terrible and inefficient support because Apple released no documentation of their hardware. The driver efforts are all reverse-engineered and likely crippled by Apple's hidden trade secrets. This is why even Qualcomm chips run Linux better than Apple Silicon; they release documentation. Apple refuses, because then they can smugly pride themselves on "integration" and other plainly false catchisms.
And on Intel/AMD, Apple was well known for up-tuning their ACPI tables to prevent thermal throttling before the junction temp. This was an absolutely terrible decision on Apple's behalf, and led to other OSes misbehaving alongside constant overheating on macOS - my Intel Macs were regularly idling ~10-20c hotter than my other Intel machines.
I have no doubt you have good information after this, but this sentence makes me not want to read any further.
And yes, your statement was a cutesy catechism with no actual evidence provided. A big reason why Apple tech doesn't work like a normal computer is Apple's rejection of standards that put hardware and software in-concert. ACPI is one such technology, per my last comment.
