It’s not exactly the same as no longer using a publisher — Amazon is his publisher. Consider this, for instance:
[N]either the author nor the online bookseller would say whether Amazon has an equity stake in the imprint.
One thing is obvious. As the traditional publishing model breaks down, Amazon is stepping into the power vacuum as an “alternative publisher.”
How will that affect writers who want to leverage Amazon as a channel? Does this put Amazon in competition with writers who would care to dispense with the middleman altogether?
