Thanks for taking the time. I figure if you run a non-hosted app that costs money (i dunno, a flashlight or camera app for instance.) there's no way to know for sure if google is being honest. I guess if you run a hosted app they would almost certainly have to be honest otherwise a user that paid wouldn't have access to your service.

It was an idle curiosity. If i ever make an app, it'll have a trivial authenticated hosted back end, just to keep google honest!
