I'm going to go with legal reasons as the likely cause. Rovio (the creator of Angry Birds), is a merchandise-whoring, cash-grabbing company. I can't say I blame them, since the plush angry bird craze is both advertisement and profit at the same time, but if they can squeeze money out of anything remotely related to them, they will. I'm guessing Al Lowe and his team didn't want to deal with any of that, so they got as close to the line as they could without crossing it.
