i don't know what the root cause is. it's most likely that linux isn't keeping up with the latest chips. maybe they need to cobble up parts from 5 years ago that do have linux support and release that. at least it would work.
1. This is a Linux-friendly laptop for the most part, but it's still built with Windows as the primary OS (and the only one you can get preinstalled). When you're building things with Linux kernels in mind, it's easy to pick current hardware that supports Linux optimally (see also: every Chromebook).
2. The places where this laptop isn't perfect are _nothing_ like the problems Linux laptops had twenty, or even ten, years ago. I used a Thinkpad with Ubuntu in 2012, and it worked pretty well... but also ran super-hot and burned through battery ridiculously quickly. The Framework doesn't do that. Sure, it doesn't have amazing battery life (around 5-6 hours), but it also doesn't have amazing battery life in Windows; it's just the nature of the hardware. The automatic-brightness thing is real, but relatively minor compared to all the rest of the hardware (Wifi, fingerprint reader, etc) working smoothly.
Apple will keep milking us until the community can come together and address the compatibility issue. We need an open linux laptop consortium that can address these issues across the board and then manufacturers can deliver a working product and compete on other dimensions, like how rounded the corners are and thin the laptop is. As it stands, manufacturs appear to be cheering they've sold 10 laptops with broken wifi! But it's wifi6e+8g revision 2023 and has a fingerprint reader. Disconnected.
Meanwhile, Apple is laser dialed on every relevant metric and they're rewarded with a closed eco-system and high margins.
