Yea, that list is painting a fairly bleak picture.
Linux kernel and all BSD are basically “lost”, which means FOSS OSs are basically lost. Arch, gentoo and Elementary (and Asahi, interestingly) seem like notable exceptions against the grain, but they are just distros.
Not sure where anti-computing is supposed to be from here?
Honestly, organising around a hard fork of a kernel and committing as a collective seems the only viable way … but we sure as hell know that’s not going to happen.
