Where, exactly, is Amazon's Unlimited plan effectively much different from a Library? Oh other than the fact authors will be getting continuous revenue, rather than only being paid for a few copies to fill the library's shelves.
Yet somehow writers managed to profit and thrive, even as libraries allowed anyone who wished to walk in and read all their works for free.
Rather than turn publishing into a zero-sum game and Scalzi believes, it appears to me that Amazon has turned the idea of a library into a new revenue stream for authors. You'd think authors would be happy for that opportunity to earn a little more income.
Sure, some authors will learn how to write books that game the system over time, but so what? This is not the only revenue stream available to authors, just one of many. Some people will pay for Unlimited, some will still buy individual books, some will wait for the movie, some will pirate the book AND the movie, some will pick it up at the library.
