You are absolutely right, the blame here really does fall on Apple. As the article mentions, the information they got from Amazon could have been obtained from a local pizza joint as well. Even so, this seems like a decent way to compromise amazon accounts. Even though the danger involved when that happens is pretty minimal for the reasons that you mention, it should nevertheless be something that concerns them. Even just things like revealing purchase history is an issue, though of course unlikely to be a lifewrecker like the Apple situation. I can't imagine this process will work with them in a few days. All I meant to say is that they have something to fix, not that they share significant blame.
