Zazzle removes mug for hypothetical copyright infringement

Instapaper creator Marco Arment used Zazzle to sell a mug. The mug was emblazoned with a fictional Amazon/Appstore-style review lampooning foolish, entitled users. Zazzle removed it because the "design contains an image or text that may be subject to copyright", and cancelled more than 100 outstanding orders. [Marco] Update: Reinstated!
