In this book, Cory Doctorow introduces and expands the concept of “enshittification,” describing how digital platforms and technology companies systematically degrade their products and services over time in pursuit of profit, control, and market dominance. Drawing on examples from social media, e-commerce, publishing, and the broader tech economy, the author explains how platforms first serve users, then business customers, and ultimately themselves, resulting in declining quality, reduced trust, and social harm. The book also explores the structural incentives that drive this process, including monopolistic power, weak regulation, and surveillance capitalism, and proposes policy, legal, and collective actions that could reverse or mitigate platform decay and restore accountability in the digital ecosystem
