Schiller then brings up how there's a complementary ad in which an Android user buys books, then reads them on iOS. Jobs' point would make sense if that was the original example, but it wasn't brought up until after he'd responded. Weird. Maybe he was psychic? (j/k)
Another thing that doesn't make sense is Schiller's recommendation to ask Amazon to "get in compliance with the rules". It sounds like they were in compliance with the rules, because an exception had been made for them. It seems (from those emails only) like the issue was that Apple made an exception for Amazon they no longer wanted to abide by.
