I think they impose enough "rules" as it is. Maybe a $3 app with adds means it doesn't have to cost $5. That's just an example. There could be all sorts of diff

I think they impose enough "rules" as it is. Maybe a $3 app with adds means it doesn't have to cost $5. That's just an example. There could be all sorts of different reasons that developers will have for both, and I like the idea of letting them worry about their business model on their own. If users hate the ads if they are already paying for the app, I think that will work itself out naturally.
