Nowadays no one needs anymore an explanation of what enshittification means, but this book provides various real cases in the IT and other industries how enshittification works and explains how it endangers societies and economies. The current human epoch is thus described as Enshittocene. Enshittification describes the natural history of companies (in the beginning only tech-companies, but nowadays all possible industries): 1) platforms are good to their users 2) They abuse users to make things better for their business customers 3) They abuse business customers to get all value for themselves 4) they have become a giant pile of shit (no benefits for anyone except for the platform owner). Examples are given in Facebook (Meta), Google, Apple, Amazon, Twitter, Uber, TikTok, but also other industries (e.g. poultry packing in the US - "Chickenization"). Key parts are heavily spying on their user base, building of cartels and subscription models as well as lock-in techniques. He reinforces that there needs competition and argues well that monopolies are bad for everyone. The aforementioned companies heavily abuse the law and promote lobbyist in all parts of the government. Antitrust law is an important mean - if designed right to avoid monopolies. Monopolies have counter-interests and invent many tricks to circumvent law (e.g. by offering service as an app). The bill for this has to be paid by consumers and society. Nevertheless, he gives existing examples how this can be fought (e.g. via the gigworker apps Para and Tuyul), gaps in existing regulations (e.g. EU copyright and IP law should not be modeled like US law), new regulations that help to increase competition and lead to better economies as well as societies (e.g. right to repair, interoperable solutions) and technical interoperable solutions (e.g. ActivityPub standard used in Mastodon, Bookwyrm etc.). The book concludes with a negative and positive outlook. This book targets a wide range of groups in society - not only technical people, but everyone and it should be seen as a corner stone to a more sovereign Europe.
