PPAs would work if they would be widely adopted by all the upstream software whose latest versions people desire AND the PPA infrastructure is adopted by all major Linux distributions so that developers don't need to package in N different formats. But as it stands, leaving it up to distribution maintainers means programs tend to lag several versions behind, while for faster updating each distribution has its own incompatible way, which means developers often give up and don't package at all and leave it to the maintainers, or just select one method like PPA or AUR. As far as I can see, Snaps/Flatpaks aim to change this, but at the expense of introducing much less manual oversight and inefficiencies in terms of storage, at the very least.
