Whatever. I just can't argue with a person that believes an ad is the same as a built-in functionality. I can't understand what kind of logic and thinking is going in your head, really.
How about we call it what it is. Advertising. However you frame it, it's advertising. Is it useful? Who cares. It's advertising. Order a pizza using the app and your telco gets paid. Twice. Being able to remove Apple's built in apps is besides the point. Yes, it's mildly irritating that this can't be done, but it's not the same thing. Pretending otherwise is disingenuous.
