Wayland and Xorg are responsible for display, Systemd is an init system, flatpaks and snaps are containerized, cross-distro packaging formats, you know what a distro is, Pipewire and Pulseaudio are responsible for audio, Vim and Emacs are editors, GPL and MIT are open-source code licenses, I can’t explain immutability.
