Well... yes. The main work described in the article is a work of fiction. i.e. a work of imagination, which means the author listens to his own inner muse. The protagonist is fiction, his experiences are fiction, his story is fiction. Lies, simply, but (if we're lucky) entertaining lies. The author is under no obligation to listen to others (especially their 'truths',) and may in fact harm his work by listening to others rather than trust his own sense of story. If he's an obligation to anyone, it'll be to the buying (and reading) public who'll decide the fate of his work.
