I feel really sorry that guy's illusions have been shattered. However, the likelihood that people are going to stop asking Rawling questions about that series of books anytime before she croaks is so close to zero as to not matter, so he's going to have to put up with it. Finally, while it's true that the characters and story are no longer solely an author's after the book's been published, they don't belong to the readers either.
Next, who said I was addressing you? I was basically talking about the delusions of control the guy who wrote the article had. Boo hoo hoo, the gestation of the characters I like so much happens to offend some deeply held/buried views I have, so the natural thing is to expect the author to stop talking about it.
Finally, I'll sass you anytime I damn well please.
