> Canonical's philosophy in some ways mimics that of Apple's where they care about usability over configurability.

The philosophy they mirror is the "Walled Garden" and "complete control over user devices" though I'm not sure if even Apple is doing the latter. I don't see any practical reason for denying experienced user the choice. Snap may be technologically most advanced software distribution solution (it is not) but it benefits only those who control it, and in case of Snap, that is not you, the user, but Canonical.
