That throws the baby out with the bathwater due to its coarse grained nature. I'm fine with having a free game using an IAP to unlock full functionality, or to have a small! series of IAPs for it. I think there's also a viable model for subscription gaming, mobile MMOs are plausible. Requiring that all apps indicate their (enforced) maximum monthly and lifetime spend limits would work very well for me. An app with a $20 lifetime limit is a try-before-you-buy app, and one with a $20 monthly limit is a subscription app. One with "Unlimited" for monthly is a freemium casino, and is much more easily avoided.
