We agree there is an urgent need to reform antitrust law and enforcement and certainly criticize existing approaches in the pages that follow. But antitrust should not be relied upon to do all the heavy lifting. In this book, we explore how the chokepoints enabling corporations to extract more than their fair share of value are formed in the first place. Very often, as we will show, legal structures outside of antitrust contribute substantially to the accumulation of vast corporate power. For example, Amazon chokes publishers by chaining audiobook and ebook titles with digital locks that are illegal to remove. (This might sound like it’s to the benefit of authors and publishers, but as we show in the next chapter, it has been crucial to stripping away their power.) Spotify does it to recording artists and labels through playlistification, which trains us to let it decide what we listen to, and by relying on fiendishly complex music licensing arrangements to keep competitors out of the market. Apple and Google get the power to squeeze game developers from their ability to control where we get our mobile phone software. Facebook and Google captured the market for news advertising by controlling all sides of the market for ads.
