I agree, Harry, the upper level has already been established in the public's mind at $9.99, so the Big Six position is ephemeral at best, inciting suspicion and boycotting at worst.
Neither the Big Six nor Amazon will be able to forge a monopoly on content. There are too many cracks. And look at the content in this case...it is the words of an author. This isn't a motor vehicle or a coffee maker. The author has thousands of choices for distribution. True, some pay better than others...
