Hm yes but preinstalling everything just meets the need of some people that dont know what to install
People like new and inexperinced Linux users, who are traditionally Ubuntu’s target audience?
Nothing stopping an experienced user like yourself from using a more hands-on distro
Ubuntu is not just preinstalled packages. You can use it for its software support, more stable releases and uninstall everything and get Apps purely from Flatpak.
I mean, why not just open software and install literally one of the apps on the main page? Libreoffice, Thunderbird, Firefox are all there.
