Why should the GUI application be a system package? Why shouldn't we have the good permission system that Android has? Why is the distro packaging every piece of software out there a good thing? Why is a couple of packages using more space a big deal to you?
I never can understand those people who are just against the idea of flatpaks. On the other hand, I can see why you'd be against it for the state in which it is right now.
Annnnd we are back at square one. flatpak is just another distro, with the limitations of a distro. You are basically asking for a unique distro to rule them all.
That's not what I am asking about; fragmentation is another separate problem. What I am asking is why would you be against the idea of flatpak, if you use snaps, then you're with the idea of flatpak (to some extent).
