Flatpak is much worse than packages because if i install a package from my distro it doesn't make duplicates for libraries and other software i already have installed. If Flatpak checked to see what i have already available and downloaded only the dependencies i do not have already installed while also providing seamless integration (a large part of which wouldn't be an issue if it used the system libraries/software), it'd actually be very useful and a solution to every distro having to package every program under the sun and keep it up to date (which IMO is also a bad thing because obviously not all distros can do that, it is just that Flatpak is a worse solution).
