How is this app a scam? It didn't promise any great functionality, you knew exactly what you were in for when you bought it.
When you look at this app you have to look at it from a rich person's perspective and not from your pauper's perspetive. For some people a $1000 is not much at all. Do you get upset when you loose a penny, probably not because you have a lot of pennies and it's easy for you to get more pennies, now apply that same attitude toward a $1000.
