> While the dominance of Internet platforms like Twitter, Facebook, Instagram, or Amazon is often taken for granted, Doctorow argues that these walled gardens are fenced in by legal structures, not feats of engineering. Doctorow proposes forcing interoperability—any given platform’s ability to interact with another—as a way to break down those walls and to make the Internet freer and more democratic.
Most notably, he retells how early Facebook used to siphon data from its competitor MySpace and act on user's behalf on it (e.g. reply to MySpace messages via Facebook) - and then when the Zuck(er) was top dog, moved to made these basic interoperability actions illegal by law to prevent anyone doing to him what he did to others.
