I like to see him argue this from the ground up. Start with the local-library model: why should Amazon pay anything for book lending? Aside from the fact that technology has made it possible?
As I recall from the three books I wrote, authors don't get crap from discount, book club, or library sales.
Is the publisher is trying to make a little extra margin for itself, by demanding a fee for loaned books? Will a standard author's contract now include an author's cut of these lending fees?
