Explanation for newbies: The GNU/Linux copypasta is an argument made by Richard Stallman that the operating system should be referred to as “GNU/Linux” or “GNU+Linux” because linux is just the kernel and what makes it useful are the various GNU programs and libraries like coreutils and glibc.
Alpine Linux is a linux distribution that ships without any GNU software (though it can be installed using the package manager).
Insisting in the GNU/Linux thing gets cringier as time passes and GNU continues to fall into irrelevance.
It has always been a terrible take, but bro, I don’t see GNU being used in mainstream distros by the end of the next decade.
I could also name like a shit ton of programs way more relevant than the coreutils.
