>The fact that it hides the actual drives makes me think that this is all intentional to have users unlearn (or not learn, if young) how HDs work and bill for that juicy cloud storage.

Isn't that just the standard nix filesystem view abstraction leaking into the rest of the OS? Your file system could be any number of drives (or no drives at all) mounted at arbitrary points. Showing them like they are any relevant place to start for most users seems silly. Especially given that in a modern nix OS, almost everything in the top level of `/` is useless to users.
