With due respect, you're giving the OP a deliberately ungenerous reading to score a point. If I tell you "I like using Dell's servers because [reasons]" you wouldn't say, "They're YOUR servers, Dell just made them" because I said "Dell's servers" rather than "Dell servers".

The trouble is with the language though, especially when thinking about who is permitted to do what with the device.

I wasn't trying to score cheap points, I was attempting to demonstrate two concepts that had been collapsed into the pronoun "their" really must be considered separately when thinking about authorization.

I apologize if the message was muddled in "gotcha" language. I aim to do better than that.

I live in my landlord's apartment. Technically, they have a key to enter. I absolutely have to trust them to ensure they don't come inside if I am not here. However, they still have to ask permission to enter (unless it is some clear and obvious emergency), as we don't consider it to be my landlord's apartment: we consider it to be my apartment; the language is trying to shift the discussion into some weird natural stance that somehow, just because Apple made something and I can't know for sure they aren't lying to me about whether they honor the restrictions I tell them, it somehow means they don't have to ask... that's bullshit :/.
