That’s not an analogy. We’re not talking about self service - we’re talking about the red herring of taking batteries from new iPhones to put them in old ones.

That’s not an analogy. We’re not talking about self service - we’re talking about the red herring of taking batteries from new iPhones to put them in old ones.
