So what...it's a joke in poor taste from a publicity hungry author and stand-up comedian. I've seen worse. Actually I think he is pretty funny. As far as standup goes I'm guessing you would also find Lenny Bruce unacceptable.
As far as him resisting ebook sales, it was a figure of speech most likely. Authors don't have that level of control over contracts unless he's JK Rowling. Publishers have had audiobook and ebook clauses in their contracts for years now, so most of his books would be grandfathered in under that.
Writing letters to his publisher - now that's funny!
