The proprietary store backend really isn’t consequential. Most websites are, and if you have a modern computer, you’ve got proprietary firmware running at ring -3. At best, it’s a distraction from Snap’s real issues.
Snap packages are compressed filesystems, similar to squashfs. When an application is started for the first time, the filesystem has to be decompressed and mounted to the root filesystem, which (depending on the computer) can take a long time. It also litters your mount points with loopback devices.
Snap’s sandboxing only works on systems running Systemd. No Devuan, no Artix, no Alpine; the packages will work, but without sandboxing.
The worst part is Canonical’s desperate attempts to make snaps happen.
Ubuntu ships with a modified apt that first checks if the desired package is available as a snap, and if so, installs snapd and the snap package without asking or even notifying the user. Strike that, it’s even worse. https://feddit.uk/comment/20490326
Canonical has forced other official flavors (Xubuntu, Kubuntu, etc; to note: they’re not maintained by Canonical) to ship their systems without Snap’s direct competitor Flatpak out of the box. https://www.omgubuntu.co.uk/2023/02/ubuntu-flavors-no-flatpak
…and I’m sure there’s more that I’m forgetting about.
They haven’t modified apt; they abuse an extra version number that supercedes the major version number of a package. I think it’s meant to be used for new packages that reuse the name of an abandoned project. Canonical publish packages for software like Firefox that depend on snapd and just run snap install firefox instead of actually installing anything. Since they bumped that extra version number, their packages always have a higher precedence than even the officially packaged debs from Mozilla.
What’s even even more fucked up is that the package still installs an executable to /usr/bin/firefox, but it’s just a wrapper script that launches the Snap application… and also replaces your desktop shortcuts, application launcher shortcuts, and favourites with its own Reforged Edition file if you’re running GNOME, Unity, MATE, or KDE Plasma.

That’s not the full picture.
