Are you bothered because a fan will run around with a fluff helmet ? seriously. Fluff items to buy were in the game since the very start at launch even (BlizzCon pets).
It is not because you buy coca cola every week you can have all merchandised coca cola things for free either.
You don't have to pay for a WoW mouse mat either, nor just another in game pet. And some fans paid 500 Euro or more for a spectral tiger 6 years ago already... Did it hurt ?
