From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Can someone please eli5? Why do I never hear anything about the window manager in windows and macos? Why is all the fuss on our side on Linux? I'm genuinely asking.
A compositor is a program responsible for displaying program windows and things like the desktop on your PC. On Linux, the compositor is just a program that starts when the system starts. There are multiple desktop environments available, like Plasma or Gnome, each comes with their own compositor, you can choose which you want to use.
Wayland is a protocol that the programs use to communicate with the compositor. Everyone decided to use Wayland, because if each compositor had their own protocol it would be silly, eg some programs would work only on Plasma or Gnome.
It's a replacement for a much older X11, which could no longer keep up with requirements of modern apps.
You never hear anything about compositors on Windows or Mac because there's only one available, you can't choose.
Actually, Windows does allow you to use an alternate “compositor”— a feature which is used quite frequently in the industrial/embedded space. Windows calls them “custom shells”. The default is Explorer, but it can be set to any executable.

Oh man, brings me back to blackbox / xoblite on my old XP machine.
I remember using notepad to change the config files, no auto formatting or error checking.
Had no idea what I wanted out of it but I loved the minimal aesthetic.
