And this is why, eventually one gets tired of all reboots, and endless variants on Distrowatch, get a computer at BestBuy, Mediamarkt, Dixons, or whatever is the local chain, run GNU/Linux on a VM, and be done with it.
Basically, had it not been for AT&T lawsuit, or Microsoft losing interest with either Xenix or Windows NT/POSIX subsystem, and Linux would hardly matter.
You're pointing out, in other words, that UNIX/POSIX is what matters, regardless of the package.
For me, one of my favourite things about Chimera Linux is that it is both everything I want from Linux and 100% immune to being called GNU/Linux.
Chimera Linux: no Glibc, no GNU utils, no GCC, and no Systemd. As a user, I am finally free.
We should consider “freedom from being labelled GNU/Linux” as “the 5th freedom”.
