It's so upsetting that Ubuntu went so hard in on Snaps. I just end up with issues caused by their sandboxing with hardware and config access and you end up having to fight to find a normal .deb install for FF instead of that damn default Snap.
I hope the journey isn't too rough for you though - best of luck!
If you want to easily distribute commercial applications, use flatpak. You could even have your own flatpak repo for your own products, if you wanted (it is really just static http).
I agree that the flatpak/appimage/snap options for apps, and in particular commercial apps is a decent idea. I think integration and permissions should probably move to something similar to the UX for phone apps though... it feels weird having to try to configure permissions that should be in the box.
