I don't see how this is a given. Monetization is no simple task, otherwise Snapchat etc... would have a fairly straightforward way of implementing it without disrupting the core business. Last I checked there is no good strategy and the in-app purchases doesn't seem to be working that well outside of games. The idea of push ads like they are doing with their snapchat self-promotion stuff is a recipe for disaster from unsolicited companies.
