Is the Snap backend available and open-source? If not, then it’s antithetical to software freedom because Canonical is trying to close their users into a walled garden in the ways that Apple and Google are with their app stores.
There are plenty of software packaging systems that work just as well or better than Snap, and promote software freedom (Flatpak, Appimage, or even just traditional package managers). By using and promoting Snap over these, you are working against the growth of digital rights.
