With so much user-generated content being placed onto the PlayStation Network through Game 3.0 titles, like SingStar and LittleBigPlanet, it's unsurprising that Sony's terms of use have a clause that allows them to redistribute and use user-generated content without compensation for the original creators. "You authorize and license SCEA a royalty free and perpetual right to use, distribute, copy, modify, display, and publish your User Material for any reason without any restrictions or payments to you or any third parties."
For example, Sony could show off your latest LittleBigPlanet level in a commercial they air. Or, they may show off your amazing drunken SingStar vid in a magazine ad. Maybe they'll make money off ads that run in your private apartment in Home. There are a lot of possibilties.
However, there is one fear, as pointed out by I have the Princess. Could Sony also redistribute user-generated levels from LittleBigPlanet as paid DLC? If so, there's no entitlement for the creators to gain a single penny off of those purchases. We doubt something this drastic will happen. Instead, we still believe LBP creators might, just might, have a chance to get rich off the game.
