I'm not trying to attack him, but this is pretty funny.
Context: 11 days ago DT released a video where he called out the people who refer to Linux distributions as "Linux" as opposed to "GNU/Linux". Today he released a video where he did exactly that.
Indeed. "Linux" now means "literally Linux, the kernel" and also "an operating system that uses Linux as the kernel". Kind of like how people say they use "Windows" but they mean that they use "Windows 11".
The only reason saying "GNU/Linux" helps is if you want to give credit to GNU. It doesn't add clarity to anything. Which is warranted, but also, what if I forked GNU and relabeled it as linux-tools. I believe that's within my right, isn't it? To fork and copy things.
It's kinda odd to be like "copyright is bad, the works should be free, and just pass around naturally!" ... "but also make sure I get credit"
I've come to realize that semantics are vastly more important than many of us realize.
Saying GNU/Linux isn't about giving credit to the GNU Project so much as it is about spreading the message that GNU represents. GNU represents a cooperative, collaborative philosophy diametrically opposed to the oppressive, exploitative capitalist ideals championed by today's ruling class. By using "GNU" we remind users that the freedom we enjoy with our computing today was made possible, not by a kernel, but by the ideals of community and camaraderie embedded into our software by way of the GPL.
I don't see anything antithetical about anyone wanting to share their work while at the same time wanting to be credited for it. On the contrary, most copyright regimes have specific carve outs for moral rights such as attribution. Even the most liberal of the creative commons license options includes an attribution requirement. That said, it isn't just within your right to rename things you fork, it may be a requirement. For reference just think back to the controversy surrounding IceWeasel.
To me the credit thing is less about "oh they made it so they deserve the credit", and more about spreading word about the free software movement. Software freedom is good, and GNU is all about software freedom, but people won't find that by searching for "Linux"
