Using Linux without GNU?

Alright, I get it. You're just taking the piss. Silly of me to take you seriously.

You don't really achieve anything by doing that though

Alpine linux can be set up without GNU, and its a "common" distro for routers and other headless machines

use TempleOS

Only GCC can compile Linux, no Linux distro is entirely free from GNU

tmux

I don't use tmux but how exactly is it broken?

use macOS, a capitalist unix without ganoo

He installed?

FreeBSD is systemd free. Also, you cau use clang to compile the kernel.
