Does anyone have historical snapshots of this document for comparison with previous statements about virtual currencies? The Wayback machine appears to only have redirects to the developer login page here. This is being presented as a change, but without a previous version I don't see how we can consider it one -- the language might be unchanged but have been interpreted strictly by the review process, for example by defining "approved" very narrowly. Off-topic, but I notice that the guidelines prohibit buttons for external purchase of in-app content, but as I recall, they used to prohibit buttons for external purchase of any digital content; why is why the Amazon app could not sell Kindle versions of books. I would be curious to see whether there is a change in policy or if Amazon was either being overly cautious or the restrictions were being applied more severely than a literal reading would indicate.
