I'd like to defend the article as a fan. There have been a lot of authors and lawyers discussing the issue, but not many people who seem to feel deeply on this from any other angle than legality. I may just be naive but the Harry Potter Universe is very near and dear to my heart. I love all of the forms that it comes in, and I try to make it a point to visit my favorite fansites (the Lexicon and its affiliates included) each and every day with hopes of updates.
What I cannot understand is Jo's statement that a published Lexicon would keep her from publishing her own. (If she does indeed publish and if she makes it available to the masses instead of the select few able to bid on the Beetle Bard at Sotheby's.) Who in their right mind would choose a fan-based work over something straight from the author's mouth?!? There is no way that it would diminish the profits she'd receive!
As a greedy little fan, my palms got sweaty when I read the Lexicon post that they were being published and I was incredibly disappointed when I saw that the revered J.K. Rowling was suing them for it. In my mind, she held a place elevated above other writers for her indulgence of the fandom. The fact that she has allowed fanart and fanfiction sites to remain online had given me hope. Also, I'm confused as to how this is different than the dozens of published "unauthorized" guides on Harry Potter. If I were her, I would be more offended by the books that were on shelves before July predicting the outcome of her final book than a compellation of things already published.
I know that I'm not looking at it from a legal standpoint - which was the point of the article - but I'm just a disappointed fangirl.
