I, or any other user, can replace the battery. Some choose not to, but that does not mean it is impossible.
I would never bungee jump, but that doesn't mean it is impossible.
User + ability to replace battery = User replaceable battery.
I hope that is easier for you to understand.
It would appear as you are the one whom is not understanding. I never said that the battery is not replaceable. I never said that the user can not replace the battery. I said that Apple deems the battery to be nonuser replaceable so it is factually accurate to say that the battery is nonuser replaceable.
