Apple delivers privacy from 3rd party developers and at the same time retains all that user data for itself, shoring up its unfair competitive advantage as a non-neutral-platform who makes major forays into its partners’ businesses. Eg health apps, maps, news, podcasts, imusic, etc, etc.
The main economic incentive to collect massive amounts of user data comes from two-sided market (users and advertisers). Google, Facebook are in that market.
