This just does not match any available data. Look at where Apple gets the bulk of its revenue and profits: hardware products and optional services.
Look at their investment: the bulk of it goes toward developing new products and acquiring new technical capabilities.
Look at their pay services, none of which are required. You don't have to buy apps from the App Store; many apps are available for free, including almost all of Apple's own apps. You don't have to subscribe to Apple Music. You don't have to use iCloud for backups, for photo management, for anything, really. You don't have to use Apple Pay.
Look at their open access to the Internet. You can load any website you want in Safari... don't want the Facebook app? Just go to facebook.com, it works great.
Look at their most popular service, iMessage, which is still free.
Look at their required software updates, which are all free. New iOS? Install it for free. New version of Garage Band? Download it for free.
I think people are getting confused about what "rent seeking" actually means. Apple's paid services are upsells.
Rent payments are not optional (just like paying rent for real estate--you have to live somewhere). Microsoft made tens of $billions charging for non-optional OS updates and application updates... that was rent seeking. Again: note that Apple does not charge for their software updates!
