All I have to say is so what. The entire idea of 'copyright' is to license who can print new paper copies of a work. It does not say 'only a single person can read this creative work'. The publishing industry throws these figures around so the general public thinks it's hard for the poor poor corporate publishers.
I bet the auto industry wishes that everyone had to buy their own car wherever they went, only one person could drive in the car and taxis/buses didn't exist.
