I’m gonna guess that this thread is about “why do you like Linux” similar to the Mac thread, so here goes.
Actually, I’m not sure where to start - there’s many things:
- free software: I’m not really in on the “no non-free software shall run on my computer” story, but the fact that almost everything is done in the open, by volunteers, is just brilliant to me
- customizability: Installing or uninstalling something is a matter of one
apt install, and keeping software up-to-date is equally simple. Configuring most things is just a matter of viewing the manpage for the service, updating it, and reloading / restarting the service. I know that systemd isn’t everyone’s favourite, but I like it for this exact reason: every piece of its documentation (that I need, anyways) is just onemanaway, such asman timesyncd.confif I want to reconfigure my NTP servers. - runs everywhere: I run Debian on my (second) home computer, my Raspberry Pi at home runs Debian Buster (custom Kernel), my servers run Debian, the list goes on. Learning something new on one almost always helps you with all others.
- free software, part two: Likely not super Linux-specific, but the package management probably plays into this. For most things there will be multiple projects accomplishing the same thing (in different ways) and you will rarely be locked in to using a single x or y. For instance, I’m currently messing around with
systemd-container(see systemd-nspawn - ArchWiki and / or I Challenge Thee) which is a nice and simple alternative for running containers compared to all the other solutions out there, but using something else is a matter of a few shell commands.
A big part of the reason is probably also Valve’s excellent proton which works wonders to play games on Linux, and a lot of my “Windows-only” Steam games now run on Linux without any hassles. I love it
