Is snap enough of improvement of Flakpak to ignore community standard and deal witb all the user hostile craziness like non-removable updater? No way.
I hope it goes the way of the Mir and upstart - replaced with a competitor and silently removed.
And I think that it's a grand time to slowly wind down snaps and switch to flatpak. Linux ecosystem does not need more fragmentation, and given proprietary nature of snap store, there is approximately 0% chance that anyone except Ubuntu derivatives would adopt it.
Maybe snap was better than Flatpak back in the beginning; I can easily believe that when the snaps were introduced, they were better than flatpaks. I am not going to judge. All I want to see a right decision made going forward.
