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"
I'd just like to interject for a moment. What you're refering to as Linux, is in fact, GNU/Linux, or as I've recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.
There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux!
The whole GNU thing has always came off as butthurt from RMS since Linux got all the glory while he and his team of contributors shit the bed on the Hurd kernel.
Let's not forget that X.org + all the desktop environments which are very important parts of a functioning OS are not GNU projects either. At what point do we need to say GNU+X11+KDE+Linux?
All I know is if you say that machine over there runs Linux, I know what you're talking about.
