Yeah I don’t hate Ubuntu, I used it as my daily driver for years, but it did get a bit frustrating how they seem to fixate on the new ‘shiny’ thing (Unity, Mir, the whole convergent desktop thing, now Snaps) and chase after it while other things are left to stagnate, then they seem to get it to where it’s almost good, then drop it and go chasing off after something else.
Also, I find that these days there are just better options for a ‘just works’ kind of distro (like Mint or Pop!OS) so I don’t hate Ubuntu, I just have no particular need for it anymore.
I run Steam on Arch as a Flatpak (because it tends to be pretty messy with dependencies so it’s nice to have it all contained in one place) and it’s always worked perfectly well for me too.
