The software I use most often.
I use Gentoo (a Linux distribution) on my laptop. This is due to personal desire to learn more about Linux it gives many possibilities to customize everything from the Linux kernel, init system, to the smallest gui elements using USE flags and additional parameters. The developers do not push a certain agenda, and it is possible to choose alternatives to different software, as well as compile from source to choose the fuctions wanted by the user.
I use LineageOS because I do not trust the OS that my smartphone ships with. Plus I dislike bloatware and try to distance myself from forced uninstallable apps.
