Some come to me and say, "but dude, we should give recognition to the kernel and say GNU/Linux", and I tell them I don't care about the kernel, am not saying GNU/Linux every time, it's way too long and doesn't roll off the tongue. Plus "Linux" sounds nerdy af, like, "blip bop kernel source code 00101000 10100100", while GNU's all about freedom, what really matters, being all like "am not your proprietary crap" repeated ad infinitum through the recursive acronym that is GNU, that's proper big brain stuff right there rather than technical gibberish about a kernel.
This one paragraph abode is very tongue in cheek of course, but I still mean it though.
I've spent a few years arguing for GNU/Linux or even just GNU on reddit, mostly in r/linuxmasterrace, and I was pleased to get quite a few upvotes every now and then, in a place where you can find people that will say things like "I make a point of never saying GNU/Linux, it's called Linuuux!!!111!"
Here's some comments I still can hardly believe got upvoted :

And many more but with less upvotes or less interesting.
I get why people say this, but at this point "Linux" has become so much more than either GNU or Linux proper, and even many people who are not knee deep in tech are familiar with "Linux" under that name. It's like arguing against using the name "Kleenex" for any facial tissue. Maybe it's technically correct, but common usage left the station a couple decades ago.
GNU.org argue to add GNU/, making it GNU/Linux, this way you give recognition to the initial project, the freedom concerned project, while also using the "Linux" term for its recognition.
Lots of people have replied to me along my years around this conversation that GNU/Linux is just too long, so I say if it's really too much to type GNU/Linux, might has well shorten it to just GNU. That's what I chose to do personally, what I think makes more sens and is a better choice compared to shortenning to "Linux" for the name of the system in general imo ...
