This is Comcast’s first attempt to distinguish between bits which it delivers for “free” and those it doesn’t. The company claims that “content is being delivered over our private IP network and not the public Internet,” but that’s a meaningless distinction given that Comcast owns the entire pipe and can arbitrarily create private networks any time it’s convenient to do so.
If there's one company to watch as this net neutrality thing picks up steam, it's Comcast. They have clearly been against it from the beginning, and why not? AT&T, Comcast and all of the other service providers are fighting hard against becoming what they already are, service providers. To me this feels like the unpopular kid in class shouting and waving their hands "Look at me guys, look at me!".
