There's been a lot of uproar lately amongst some indie authors over Amazon's new method of paying authors participating in the Kindle Direct Publishing (KDP) program.
As of July 1, Amazon is paying authors based on the number of pages read, not the number of books borrowed. This change is already reflected in the KDP reports.
This change puts authors of full-length books on equal footing with those who publish novellas and shorts. Under the old system, an author could publish a 20-page "book" and get paid the same amount as an author who wrote a 300-page book. The author writing a short or serial could spread out the story in twenty different installments, getting paid for each one and therefore making significantly more money than the author who published their entire story in one book.
Unless you're an author writing those shorts or serials, I don't see a reason to be upset over this change. It evens the playing field for everyone, allowing authors to get paid per page. If you've written a longer story, you'll get paid more for your work.
