Very interesting that Valve and Framework seem to be throwing their eggs in the Arch basket over Debian/Ubuntu. When I got my first computer, I installed Ubuntu because it was dominant. Maybe it still is for the average Linux downloader, but why are the Hardware companies more into Arch?

And over Fedora/RHEL. If I had to guess, it could be that new entrants find it easier to submit changes to Arch Linux packages [1]. ChromeOS also steered away from Debian-based distributions, choosing a Gentoo base.

Personally I'd also think it would be a better engineering choice for Valve to base SteamOS on Fedora Atomic, as it supports the immutable OS paradigm a lot better imo. Especially now with progress in bootc/oci/ostree.
I'd think it's because they're introducing updates to address issues w/ the hardware quickly and want a rolling-release distro so users can get the updates faster.
