Amazon and Print on Demand

Looks like the Print on Demand (POD) option for self-publishers has become more complicated. Amazon is telling self-publishers, among others, that if they want Amazon to carry their title, they must use their POD, Book Surge. However, if the self-publisher uses another POD service, they can still sell through Amazon but must use the Advantage program (with all its associated fees and commissions).
