Here is an exercise, when a police patrol car gets parked in 2nd lane, and the officier happens to buying some stuff on a nearby shop, go there and tell them nicely that 2nd lane parking is against the traffic laws and they should fine themselves.

Broken analogy? Apple is the police of Apple store.

Apple doesn’t need to say in the rules that they can do what they want, because they are the ones enforcing the rules. They can exempt anyone, including themselves, from the rules for any reason including no reason, without having to say anything about that in the rules. Human rules are not computer code, and also not mathematical. Human rules can be interpreted, bent and ignored. Sometimes at great risk, sometimes at no risk.
