You're not seriously suggesting the multiple apple subscription services were brought in because 3rd party apps became a thing?

The original iphone had zero market share on release. First one is free. Just like Appletv, applemusic, icloud storage, apple games subs....

If you think apple's approach has ever been anything else but abusing market power to maximise revenue I've got a bridge for you with microsoft written on the side. (MS are all like "We'd have been crucified for that, well not anymore!" And the race to the bottom of your wallet continues apace.)
