I own a blender made by KitchenAid. I am allowed to blend strawberries that have not been approved by KitchenAid. I can make an Onion Banana Durian smoothie if I want. Calling Apple product appliances is a slur to appliance makers
Most of these analogies don’t make things much clearer.
The closest one is: the phone is supposedly my employee - I pay its salary (to Apple), but it is asking Apple to approve everything I ask it to do, and they are the only arbiter.
(This analogy also sucks. You have to actually deal with subject matter at hand and not look for shortcuts)
