Apline is Linux/Busyibox or smth like that. However, that does not make 99% of distros not GNU/Linux.

Saying that the whole Debian, RHEL, SUSE and Arch realm (ie. stuff like Ubuntu, Fedora, CentOS, Opensuse, EndeavourOS, Manjaro etc) and countless other distros are not GNU/Linux would be as, if not more, disingenuous as calling Alpine “GNU/Linux”
