But Debs can be sideloaded and they’re less secure because they’re not confined?
I guess there’s no reason not to upload a snap to the snappy store though and it’s really not very difficult, whereas it’s more difficult to upload a Deb to a PPA (and expect users to add the PPA) or the Ubuntu repositories and keep it up-to-date…
However, if we want to enable user-friendly offline installs (and offline updates), then we need the ability to sideload snaps using GNOME Software.
