It turns out that having a book well-edited and written according to particular stylistic requirements wasn’t necessary to get it to sell well: it was necessary to get it published. And since books which aren’t published rarely sell well, editing and stylistic accomplishment were second-order requirements. Now that a book can be published without meeting them, lo and behold, books which aren’t edited and written in a particular style can sell well.

That isn’t to say that ceteris paribus a book which is well-edited and stylistically proper won’t do as well or better than a book which isn’t. It almost certainly will. But a book which isn’t and has a good story and good characters will do better than a book which is and doesn’t.
