Yeah but that's true for any market. Is there data that indicates that this happens more for appstore software? I mean I'm not asking for a peer reviewed, 1000 apps study or anything, just a plausible indication that the average appstore customer is more likely to do this and/or be influenced by blog posts complaining about price hikes. Maybe just showing that appstore customers are far above average in being likely to read and be influenced by online reviews is enough - if there is some correlation to be made between appstore customer profile and sensitivity to price hikes.
