It seems to me there is something going on here about the difference between amateur enthusiasm, and professional interest. There is a very real sense in which there is something pure about fandom that is uncorrupted by commercial interest. Folks whose job it is to work for companies that produce art or products that are the subject of fandom are always conflicted between (in an ideal world) their real passion for the thing, and their job-driven objectives to make money for the company they work for.

Civilians and professionals will always somewhat hate each other because of this. The company and its workers will always, ultimately, sell out in favor of a fast buck, the fan will always ultimately feel disappointed and betrayed by this.
