> The "common carrier" designation is easy to implement when communication is point-to-point with paid subscriptions (e.g. telephones) -- instead of broadcast funded with ads or government taxes (e.g. Facebook/Twitter, BBC). There is no government in the world that allows broadcast of any topic without interference. The paper deals with the supposed distinction between point-to-point and broadcast. In brief, it's not very clear. Consider the postal service: If millions of people subscribe to a magazine, is that point-to-point communication or broadcasting? How is it different from millions of people subscribing to a youtube channel? Or following someone on twitter?
