im glad that it works for you, but my point is that we should have the right to have a non-intrusive phone just as easily as we have intrusive ones. People shouldnt be expected to learn how to unlock a bootloader, or import one of the few phone models that support these alternative roms with all security features in place. In the process of installing these roms, some people might fall into the trap of installing them from a suspicious source.
If i got it right, flatpacks gather all of the dependencies of the package and bundles them with tha package. Maybe those extra 290mb were from dependencies that you already had installed but that flatpak wanted to install another copy.
