Should we call it X/GNU/Linux as to not downplay the work the people at Xorg put in? Also possibly Systemd/X/GNU/Linux, how about Plasma/Systemd/X/GNU/Linux, and since nowadays browsers do most of the tasks I think it’s only fair Firefox/Plasma/Systemd/X/GNU/Linux, or maybe Chromium/GNOME/Dinit/Wayland/Musl/Linux, you know what these two have in common? Just the Kernel, but you would say they’re both the same OS.
I’m not saying GNU is not great nor am I saying that they didn’t contributed or that they’re worthless. But GNU is not special, X, Systemd, and other such components are just as essentials to Linux as GNU, and no one claims they should be added to the name of the OS.
