OP must be an app developer.
To be fair if I spend money on an app and I don't like it im not gonna use it and I'm out $0.99.
Spending $0.99 on an game on your phone seems like way more money than it actually is. Until you run into the Chinese users...then it's nothing....
I love the free money from the google surveys app. Makes that $0.99 seem like nothing.
