There is nothing that prevents #nostr relays from developing algorithms that favor certain content, or that recognize the preferences of their users and forward favored content to them. Nothing prevents a relay from sending it's own messages to users with recommendations for notes, users, and/or other relays. I think it's just a matter of time before that kind of stuff happens.
Relays can also inhibit certain users and certain topics. Again, this is just a matter of time.
The difference is that the walls of the walled garden are not prisons. Any #nostr user can step outside one walled garden into another, or into the unwalled stream of free information.
