I've noticed that Apple Maps incorporated their own rating system some time ago (I want to say within the last one or two years); it's simple, just asking you to give a thumbs up or thumbs down on certain businesses, sometimes with a bit of granularity (e.g., rate the atmosphere, food, value, and service separately). There appears to be some threshold for how many ratings they have when they switch from displaying Yelp reviews to their own stuff, although it's not clear what the heuristic is.

Anyway, tl;dr: I think they're working on replacing Yelp.
