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-
A name is just a simple reference to a system composed of interrelated and essential OS components: Kernel, windowing system, networking tools, virtual memory, user interfaces, the list goes on…
Yes GNU is an essential suite of tools but so is X (or Wayland) and many other unnamed yet critical subsystems.
Now GPL licensing on the other hand, THAT is a foundational precept to FOSS that deserves sole credit back to a single project.
I was talking to my dad about my job and how people don’t know how to use Linux. He said “Yeah, nobody uses that UNIX stuff anymore.”
Then I pointed out that his phone and his computer both run flavors of UNIX, since he’s been using Apple products since I made him switch by not supporting his issues with Windows, and that most of the websites and apps he’s using are running Linux on the backend.
Well, he is correct. Linux is not UNIX. It is UNIX-like system. And Android is abomination.
I think macOS is actually Unix certified. It at least was at one point.
At one point many years ago. BSD is true UNIX btw.
