Great book, with an encompassing theory on how corporations (especially in the arts and creative media) strive and succeed to create a bottle neck or choke point for consumers to eliminate choice and squeeze as much as they can from both consumer and creators. Loads of examples, Spotify, Amazon, Disney, attempts in other industries. They offer concrete examples, ways to improve and concerns if we don't address it. Excellent book, one that all citizens and consumers should read and put into action.
