This is entertaining.  The gist:

[Anonymous'] disguise is earning big bucks for a major media conglomerate. Warner Brothers, the Time Warner subsidiary who produced the movie, owns the rights to the Guy Fawkes mask – and they earn royalties on every sale. (Obligatory disclaimer: Time Warner is also TIME’s parent company, so in an extremely roundabout way, we’re also profiting from this.) While Time Warner hasn’t released any data related to their earnings from the masks, it’s safe to say that the hundreds of thousands of Guy Fawkes masks sold each year helps to bring sure profit to the company.
