Apple recently refused to carry an ebook in its popular iBooks store because it mentioned a huge ebooks competitor -- Amazon.
"This is not professional behavior from a professional market," said Lisle. "And cold moment of truth here -- you cannot write a writing course that includes information on publishing and self-publishing and NOT mention Amazon. It's the place where your writers are going to make about 90 percent of their money." Holly Lisle
Lisle submitted her book to Apple's iBooks store, and received a rejection letter stating that she wasn't allowed to have live links to Amazon inside. She then removed the links and resubmitted the book, only to receive yet another rejection letter. The reason? She wasn't allowed to mention Amazon at all in the book because it is an Apple competitor.
Apple rejected a book called "How To Think Sideways Lesson 6: How to Discover (Or Create) Your Story's Market" by Holly Lisle.
