Steve Streza, with a great look at how pushy Apple has become with its services:

[…] Apple has resorted to insidious tactics to get those people: ads. Lots and lots of ads, on devices that you pay for. iOS 13 has an abundance of ads from Apple marketing Apple services, from the moment you set it up and all throughout the experience. These ads cannot be hidden through the iOS content blocker extension system. Some can be dismissed or hidden, but most cannot, and are purposefully designed into core apps like Music and the App Store. There’s a term to describe software that has lots of unremovable ads: adware, which what iOS has sadly become.
