Because this matters: https://haydenjames.io/remove-snap-ubuntu-22-04-lts/

I've been getting "Firefox is updating in $time days" as a unstoppable notification, because snap uses highest priority to jam notifications through.

The best is to purge snap completely from the system. And the URL applies to 22.04, but likely also works mostly the same, with possibly more "snap list" crap to remove.

If I could properly administrate snap, and if it followed my settings, I'd use it. But it doesn't provide for ANY sort of reasonable administration nor respectable defaults. So it gets the axe.
