It turns out that when you pay for a mobile app, you're not actually buying the game. You're just paying for the company to allow you to play the game as long as the company sees fit. http://www.rockbandaide.com/16083/rock-band-ios-app-no-longer-playable-after-may-31/ The mobile version of the game Rock Band is being disabled on users devices on May 31st. The weird thing is it's still being sold in the app store. As far as I can tell, it's not just that the game will no longer be supported, but it will be completely disabled. Can you imagine if other purchases worked this way? Imagine if Chevy put a boot on your car and removed the engine because they no longer were selling that model. Or imagine if a musician got into a dispute with his record label, so the label came to your house and took away the CD you purchased. It's a wonder how this is legal.
