Switching to Debian or Arch or Fedora or Gentoo is one solution, but it wouldnt be practial for the 'not so advanced' users (the ones that like Ubuntu/Unity). I think more and more we need GNOME OS or KDE OS to become a thing. Hopefully they would be as simplistic as the ubuntus, free of spyware and the like, and kept up to date (maybe even rolling releases). This way we would have a choice thats not built on Ubuntu, like Mint, but would still be popular (hopefully lol).
Or am I just making stuff up ?
