Cause Snap is proprietary and the repo is controlled only by Canonical/Ubuntu.
Flatpack on the other hand allows for third parry repos. And then one might even preference a classical install because ironically its snappier - faster - especially on oldee setups
The snapcraft webserver backend is closed source but everything snap adjacent that touches your computer is open source, and you can distribute snaps and install them without using the snap store

But you can install multiple app stores, right? This is just one. My understanding is that it also adds sandboxing to any snaps you installed.
Snaps have sandboxing but only on Ubuntu I think. Flatpaks have sandboxing too but that should work in every distro.
