True, but it's the "first part" (since GNU runs on top of it) so I call it Linux/GNU.
GNU provides the user space, and a bunch of command line utilities, but that's pretty useless these days without a GUI. So mostly I call it Linux/GNU/Gnome.
I do spend quite a bit of time in a browser though, I mean a machine that can't browse the web is pretty useless. So my friends refer to it as Linux/Gnu/Gnome/Firefox.
Of course to have a good experience in the browser you need an Adblocker. Adblock Plus is the one I use.
I've instructed all the people in the office to call it Linux/Gnu/Gnome/Firefox/AdBlock Plus. Recently though I had to chastise someone for leaving out the word "plus". I mean what are we, Barbarians??
Clearly, considering you are using AdBlock Plus instead of uBlock Origin :)
Instead, people get interested in something new and interesting. Then, for a proportion of them, some stranger will come along and language-police them.
If you believe in free software or some variant, don’t put pointless barriers in the way of people adopting it.
Why isn't it GNU/Linux/SystemD/Mesa/Xorg? Basically every Linux desktop could be described that way.
Heck, if Earth didn’t exist, Linux wouldn’t have happened, so Linux/Earth/Sun/Biology/Torvalds/Stallman/SystemD/Mesa/PulseAudio/Wayland…
GNU nowadays is a tiny part of the desktop. There’s also projects slowly moving to rewrite it in Rust and a more permissive license, other parts are losing importance like GCC losing to Clang, so its relevance is dying over time. Just like the FSF.
