If Apple were to allow purchase of digital products, such as gems in a game or a monthly subscription to a weather app, what measures should they need to put in place to protect users? A benefit of the current mechanism of in-app purchases is that each in-app product is reviewed and approved by Apple. I'm all for opening up the platform where it leads to greater innovation, choice and competition. But I wouldn't want to see scams and other predatory behaviour making the App Store a more dangerous place for the unwary or less knowledgeable.
