I think you are mis-reading him and reading an insult that is not there. He is not even talking about epublishers at all. He is talking about commercial publishers using the ebook format, and that it is a good thing. And I agree.
"An e-book distributor is not a publisher, but rather a purveyor of work that has already been created. In this way, e-books are no different from large-print or paperback or audio versions. They are simply the latest link in an unbroken editorial chain, the newest format for one of man’s greatest inventions: the constantly evolving, imperishable book — given its definitive form by a publisher."
As I read it, he is not talking about an epublisher, but an ebook distributor, like Amazon/Kindle, ARe, Fictionwise etc. Epublishers would act ion the same way as Randon House in this scenario--but he is not discussing them at all.
