Oy. Just reverse what this article says. Traditional economics (on the left esp) was HIGHLY concerned with network effects - railway and electric power monopolies etc, and eventually closely controlled them. But we aren't as smart as our great-grandfathers, so we've let public utilities (such as Facebook) and network-effect and lock-in monopolies (too many to name) run absolute riot. It's an old term, "Railway network," and it means what it says. The Sherman Antitrust Act was used, for example, in 1904 to dissolve the Northern Securities Company (a railroad holding company). They knew well how pernicious network effects could be, from experience. We're just catching up.
