... and people are looking forward to signed UEFI and ACPI on ARM systems too. How do they expect an ACPI written in a chinese sweatshop will work if Asus quality is this low?

I assume all of these gaming laptops are largely developed by outsourced sweatshops today so I don't imagine much difference.

The firmware is amalgamated from a bunch of vendors with core solution coming from few common ones.

Sometimes you get hilarious errors, like Intel not having any way to verify if their driver is actually loading a dumped memory image (intel rapid start), so if you forgot to disable Rapid Start and installed anything on a drive in the bay that was specified for rapid start, on boot the intel driver would just... blit it into RAM and be happy dumb

I don't follow. My X13s is a Snapdragon, has full uefi, and works like a normal laptop, mostly. It can't stop from overheating and has no cooling but that's besides the point.

Open source devicetree + u-boot can be maintained independently of any manufacturer's support.
