This really should be included in the piracy debate. For example one would argue that was 100,000 in lost sales/revenue and that had the app never been available for free that 100,000 (or near that amount) would have paid for the app at full price. This is utter BS and is reflected in users revealing that they grabbed the app when it was free mostly for the sake of having it, even if they never used it. On a side note it looks like the exposure the app received generated an additional 130+ sales over the course of the month and beating out their total sales before the app was free the very first few days after the exposure.
