"The OS" doesn't exist. The operating systems you're talking about are called Debian, Ubuntu, Arch, Fedora, RHEL, etc etc. The main work of making an actually usable OS from the various free software components others have written has always been done by the teams responsible for these products.
But we still need a way to refer to them collectively, and it used to make sense to call them "Linux" because they were pretty much the only operating systems that used the Linux kernel, but now that Android is the most widely used OS on the planet, it doesn't anymore, and this alone is a reason to say GNU/Linux unless you want to include Android.
Hört auf, Dinge zu posten, von denen ihr denkt, dass sie falsch und nicht lesenswert sind. Das gibt dem nur mehr Aufmerksamkeit. Es hat gereicht, dass ich es vorgestern in den Mastodon-Feed bekommen hab.
ahhh i remember being a bored teenager spending his life customizing his desktop too...
Nowadays I just want a working system where I can get things done, haven't touched my desktop environment settings in a while and certainly don't use things like cubes or wobbly windows anymore.
Because DOS and later Windows used to be the only OS that was relevant for IBM PC compatible systems. Only later were eg. Unix-like systems developed for them.
