The traditional understanding of monopolies does not seem so useful in this case. We live a world where there are two walled gardens that control everything you do. They are both lovely and nice, and you can choose which you pick, but in both, everything you do owned by the landlord. Even how we communicate is controlled, and talking to people in the other garden is degraded. (iMessage and FaceTime). Even if both walled gardens have 50% marketshare, there is no monopoly, but is that really the world we want to live in? Taking your business to the other walled garden is not an incentive to either company to build shorter walls. It seems we need to be talking about regulating vertical integration and walled gardens, not monopolies.
