No, it's not like Amazon at all. If I buy a book at Amazon, I can give it to my 11 year old when I'm done without her having to sign on to my account. If I buy a song through iTunes, the only way I can share it with my child is to have her on my account (or buy it twice).
That's not what I was talking about. I wasn't talking about sharing. I was talking about a visible purchase history. People are expressing outrage that Apple shows your entire purchase history to you. So does Amazon.
