I think what they’re trying to say is something like “If you want to act in protest against bloat and planned obsolescence you can use a Linux desktop other than Ubuntu”
Indeed. To use a snap to install something that is pretty much integral to the Gnome desktop and has no dependency on anything other than Gnome, this is ridiculous.
Snaps are useful for packaging dependencies that aren't (AND CAN'T in a timely fashion) be provided by the distro.
