Normal publishers filter books for many aspects that would lead a reader to not want to read the book. While it's true that not much filtering is done on accuracy and integrity, the aspects that the books are filtered on are still ones that typical readers care about. Relying on the user's lack of knowledge of the publisher to make him think such filtering has been done, when it has not, is dark arts, deceptive, or whatever other term for bad things you like to use.

In other words, "I'm not tricking a user into reading an inaccurate book, I'm just tricking the user into reading a boring and poorly written book" isn't an excuse.
