I think that's fair. 301works.org[0], for example, requires its members to upload their DB to Internet Archive, but IA keeps it private. They then ask for the technical control of the domain to be transferred 301works.org in the event of the site's closure so they can continue serving the traffic. I do think that, however, that a service can keep their DB public _iff_ users know that's the case before creating links. Often times, folks are just shortening public links, but it is true that people sometimes share "private" links (e.g., Google Doc private links, etc...) which shouldn't be enumerated.
