[update]: I have been made aware that “Free Market” has been pulled from the store. As much as I would love to think this article had an influence, the important thing is that the topic of maintaining the Windows Phone eco-system as developers, is discussed.
Earlier today I was made aware of the Windows Phone app “Free Market”. Nothing unusual about that; I look at tons of apps all the time. However, this one made me half cringe, half sweat. Basically, it is an app that allows you to search the Store for an app, and then the app will check every single location to see if the app is free in any other market.
