> Even though Fedora is (afaict?) the best supposed Linux distro

As someone who had a 12th-gen mainboard and upgraded to an AMD board, and assuming you meant "supported" here, the rest of the points here are fine but this one rather explicitly is off. Ubuntu is the primary supported distro across the board: https://frame.work/linux

Fedora was recommended for AMD mainboards when Framework started shipping them, because Fedora ships newer kernels sooner, which got upstream AMD compatibility fixes out faster, which meant Fedora users could install Framework's firmware, driver, and BIOS updates sooner with fewer workarounds.

When Ubuntu 22.04.3 LTS shipped a 6.2 kernel in August, it went back in front across mainboards.

There isn't really anything on that page says Ubuntu is the primary supported distro and Fedora isn't. They seem to both be equally supported with no preference according to both the listings and the wording on the page.

Where does it say Ubuntu is preferred? When I got laptop (verified w/archive.org) the list even explicitly ranked Fedora above Ubuntu wrt ease of use
