In the case of the native Tile and Airpods, though, Apple is using their walled garden to provide an experience that's pretty strictly better than what you'd get from competitors. It's not a hole in Apple's OS per se, it's more like a privileged route to the OS.

For your analogy, it'd be as though the Starbucks owned the street the two shops were on, and gave the entrants to the Starbucks a privileged position on the street.
