Book editor Chuck Toporek has an interesting theory about why Amazon has not complained about Apple's new subscription rules for iOS. The company may be preparing to shift users to the web-based Kindle system it unveiled as a "beta" back in September.
The point I’m trying to make here is that the reason we haven’t heard Jeff Bezos screaming about this recent change to the IAP rules is because Amazon isn’t worried. They have a solution already in beta testing and it works just fine. Instead of using the Kindle app, iOS users can just point Safari to Amazon’s site, buy the Kindle ebook, and read it right there in Safari. No app required.
