I just installed Pop!_OS and kept the customization to a minimum. I don’t love GNOME, but I wanted Pop!_OS for the supposed better (easier?) NVIDIA support. I prefer KDE plasma, but GNOME works just fine. I would not be surprised if I ran into some issues in trying to change my DE. I do mess with Linux more sometimes, but I usually use a VM or some other machine for that. I don’t want to break my daily driver.
Do linux and privacy focused consumers actually make up a large portion of their market share? Linux users still make up a small portion of desktop users, and not even all of those really care much about privacy.
