. . . Anything the publisher does for a writer is incidental to providing books readers will want to buy.

Ironically, the way one knows a self-pubbed novel is a success is that it gets picked up by a commercial publisher.
The first part I quoted above (which I bolded) = words to live by. That is a splendid statement. I'm going to quote it in an upcoming talk to a writing/publishing group (with the understanding that the statement pertains to real publishers, not the likes of PA, of course).
The second part quoted above is probably a superb generalization, but does have exceptions, IMHO. Frankly, I cannot cite a whole
lot of exceptions off the top of my head, I grant you! But Naida West's success in selling tens of thousands of copies of her historical novels (she explicitly rejected commercial publication) is a counterpoint. And the definition of "success" can depend on viewpoint. Niche novels might be unsuitable for commercial presses but still successful in terms of the authors' audiences and goals. Bill Pieper's novels might be a good example:
Gomez, for one, a fine literary novel with a San Francisco regional tilt. Still,
The Bum Magnet, by AW forums participant K.L. Brady, initially self-published and recently picked up (in a two-book deal) by a major publisher, certainly illustrates your point.
