> All it takes to get rid of snaps forever is `sudo apt purge snapd`.

That's not enough. Some package could eventually drag it back in.

    $ apt show firefox
    Package: firefox
    ...
    Pre-Depends: debconf, snapd

If you really want to keep it off your system for good, you need something like this:

    $ cat /etc/apt/preferences.d/no-snapd
    Package: snapd
    Pin: release a=*
    Pin-Priority: -1
    $
