Snaps also create extreme litter in filesystem, some programs like Firefox are broken in confusing way by updates (new tabs are crashing without explanation, part of old tabs crashes), some programs like Telegram were completely broken at some pint in highly confusing ways...
Also, as mentioned by others - Snap is a proprietary, walled-garden system owned by Canonical.
What made me drop snaps is it wouldn’t let me access files outside of $HOME no matter what I tried, and the snap decided I was running Gnome instead of KDE no matter what I tried, going back to the .deb worked perfectly.
