This is not correct.

Snap is preinstalled on all official Ubuntu graphical editions.

However, Xubuntu's _Minimal_ install does not include any snap packages at all, not even a browser. This means it's trivial to remove snapd:

sudo apt purge snapd

Then you can install the `extrepo` command, and use it to install Firefox ESR direct from Mozilla's repos, or Chrome from Google's repos.

Once it's online you can copy and paste a couple of commands to "pin" snapd and prevent it from being reinstalled. Then you can switch to current Firefox or anything else without snapd sneaking back in.

Xubuntu Minimal is also available as a separate ISO file, which is not true of any of the other flavours.
