Apple Books *requires* authors and publishers to wrap their books in Apple's #DRM, and the #DMCA makes it a felony to supply *your own readers* with a tool to convert *the books you published* to a rival's format. That means that readers have to surrender every book they've bought on Apple Books if you switch platforms and ask them to follow you. It's not just #SocialMedia that turns creators into #DigitalSharecroppers.
