Game theory doesn't support "pay what you want" really well, e.g. there's no market to somehow arbitrate the price. A true market could be created by enabling people to buy and sell the service, or perhaps by bidding. This doesn't work unless the supply of the service is artificially restricted (otherwise the price goes to near zero immediately). Of course, some argue that the "true price" of intellectual property is very close to zero, but the app in the article can be thought of as a service.
