Amazon Introduces "Pay per Page turn"

As absurd as it sounds at first blush, it’s true.  Amazon has introduced Kindle Unlimited royalties based on number of pages read:

Beginning July 1, 2015, we’ll switch from paying Kindle Unlimited (KU) and Kindle Owners’ Lending Library (KOLL) royalties based on qualified borrows, to paying based on the number of pages read. We’re making this switch in response to great feedback we received from authors who asked us to better align payout with the length of books and how much customers read. Under the new payment method, you’ll be paid for each page individual customers read of your book, the first time they read it.

The Atlantic explains the motivation behind this strategy.

Amazon’s letter to writers who publish through its Kindle Select program explained that the formula was changing because of a concern “that paying the same for all books regardless of length may not provide a strong enough alignment between the interests of authors and readers.” Amazon is being clever: While the authors of big, long, and important books felt that they were shortchanged by a pay-by-the-borrow formula, they probably didn’t expect that Amazon would take their proposal a step further. Instead of paying the most ambitious, long-winded authors for each page written, Amazon will pay them for each page read.

 One can’t help but wonder.  Is this royalty adjustment a striving for fairness for authors of large tomes?  Or is this a writing incentive for those same scribners to pad for payment?
