Instead of fixing fundamental problem, flatpaks/snaps bring the whole new layer of crap and hacks. They try to solve real problem, but the way they do it is like reanimating dead body cells via cancer. But that's not even the worst part.
They can lead eventually to "Microsoft Linux Store". Canonical pushes snaps for a reason and they are partnered with MS. Flatpacks essentially follow the same route and can be embraced, extended and extinguished, and we'll be left with bare kernel+glibc distros and the rest available for 20$ in Steam/MS/you name it store
