I bought this book because I heard Becky interviewed on the Ubuntu podcast. It's an excellent read. It really opened my eyes to a few things. 20 years ago the internet was a wild west where everything was possible, people were starting businesses, people were expressing themselves freely. Today our web experiences are dominated and controlled by a handful of (American) companies: Facebook (controlling our social interactions), Google (controlling what we find, and don't find when we search online), Amazon (dominating online retailing), Apple (control freaks) (sorry Microsoft, you don't even make it on to the bad-list!)
Becky talks to a lot of people who are trying to keep the idealism alive and ensure that these companies don't accumulate even more power.
Overall an excellent introduction to the issue of freedom online.
