Film studio mistakes single mother for billion dollar competitor

In another case of mistaken identity, a studio has confused a single mother throwing a Halloween party for a billion dollar competitor infringing on their copyright to make a few more million without having to put in the hard work. Unfortunately for the studio, what has actually happened is that they have lost a golden opportunity to increase sales and customer following and instead dented their reputation. They should have done nothing. For once they would have actually prospered by doing no work and instead sat on their well-endowed backsides and counted Porsche's in the office parking lot below their ivory tower.

So what am I on about? I am talking about the case of the single mother in London who was going to host a Harry Potter themed dinner party before a cease and desist was handed to her.
The initial reaction from reading this article is that Warner Bros are nothing more than party-poopers, but actually they are far more (or less?) than that. They come across as totally ignorant. Firstly we find that they are trying to shut down any form of piracy through ridiculously high-dollar lawsuits. If you have read Chris Anderson's book Free they would have found that it is near impossible to stop piracy and so they should embrace it as a marketing tool to sell other products. But the second error is that when someone wants to actually embrace the brand they may only do so as long as they do not amplify the fact. It is that old nutshell, Command and Conquer.

What it shows is that in this "new world" the most engaged fans of a brand will put their reputation on the line by recommending it to their peers. Those peers will then pass it onto their peers if they feel it is worthy and so on and so forth. If you cut off or silence your fans you are effectively cutting off your head.
So Ms Marmite Lover should have been praised, supported or at least left alone. If Microsoft, the kings of litigation, are trying to get people to throw parties for a piece of software, you would have thought that even the studios would have jumped on board that one. After all, original ideas are not their forte.
