"54% control of America's high-speed internet service, in their utopian Metered Billing, Hugely Profitable dreams, will surpass every other line of business Comcast is in.'
Except without their own content (which NBC Universal represents), they can't discriminate since now every party is a third party, and any discrimination in favor of one will result in all the others crying foul. In fact, it would be in Comcast's fiduciary interest to fast lane NBC content and throttle Netflix (as the former is cheaper to send down their pipes). Like railroads owning their own timber plots and mines.
You mentioned Cox. Funny that. They haven't introduced metered billing, yet they've doubled all their Internet plans without raising prices (which incidentally have held steady for several years). The bill only went up about a dollar this year due to tax hikes (and remember, comm bills are itemized—by law).
Then there's the matter of Google, who none of the standing companies can bully.
"We should be writing rules that allow competitors to use existing, paid-for cable runs, and eliminating monopoly restrictions to allow new competitive infrastructure."
Two problems. One, nearly all cable in the US is privately owned. Forcing a company to allow competitors to use their bought-and-paid-for equipment would never fly in Congress, as it's a violation of the basic principle of ownership and property. Basically, it would be Un-American. Second, the reason those monopolies exist in the first place is because no one's willing to wire up as space a country as the United States out of the goodness of their hearts. They (and their investors) will demand RoI. As for muni broadband, most communities lack the capital to do it. Leaving them pretty much with a choice between an exclusive contract, an exclusive contract, or no broadband meaning you can't attract people into your community. Oh, you have exceptions like that country east of Seattle, but that's pretty much a matter of luck (being up north attracted data centers--less cooling costs--the same can't be said down in Arizona), which is why you don't see the same things happening elsewhere in the country.
"If you are a consumer, and not a shill for the cable and telephone industry, why would you disagree with free enterprise?"
Because free enterprise is willing to let the little man (or in this case, the Middle of Nowhere) rot. In the private sector, some customers are "Not Worth the Money," which to them means expendable.
