This news report suggests that some cable companies are actively blocking certain kinds of traffic on their networks. The target of such blocking is peer to peer file sharing, in which the subscribers are often sharing very large files like movies and TV shows. From a network operator perspective, what you see is a very small number of your customers using a disproportionately large chunk of your network bandwidth, which can degrade service for other customers and increase costs.
Of course, the whole issue of net neutrality comes into play here, where the argument is that Internet access providers should not block traffic or offer preferential treatment to certain kinds of data over other kinds. But the access providers are on the horns of a dilemma, because the peer to peer sharing does have a measurable impact on their network.
But almost all of the arguments for and against traffic blocking, the rights of access providers to manage their own traffic, and free speech issues are red herrings. The real problem is the outdated and obsolete business model that nearly every access provider is still using.
It made sense, more than a decade ago, to sell bandwidth by the bucket to users because all folks were doing back then was email and some light Web browsing. And the Web in the mid-nineties was most text and a few pictures. Today, the media-rich Web is filled with sound and movie files of all kinds, and everyone uses them--look at the popularity of YouTube.
The current business model does not provide any cost information to consumers; that is, the "cost" of downloading a few emails is exactly the same as the "cost" of downloading an entire movie in DVD format. This is a classic and well-understood economics problem. Current pricing, to users, makes it appear as if there is unlimited supply (of bandwidth), which in turn creates unlimited demand.
The solution is simple. Rather than trying to discourage customers from doing things they want to do, you change the pricing model so that it conveys more information about the real cost of downloading things like movies.
In other words, you move from a business model of networks based on bandwidth, which we know is not working, to a business model based on unlimited bandwidth but where pricing is based on the service you want to use. So users that like to do peer to peer file sharing subscribe not to a bucket of bandwidth but instead subscribe to a service designed specifically to support high performance file sharing, and the price of that service will be based on the real cost of providing the service.
It is simple economics. Communities like Danville, Virginia are already rolling out networks that do this. These multi-service, open networks support real competition and will start driving innovation on the network because the business model support innovation, rather than stifling it.
