A quick reaction to the court decision that the FCC cannot currently prevent Comcast from telling subscribers where they can and cannot go on the Internet: This is what happens when private companies own infrastructure.
Comcast owns the pipes so it makes the rules. The FCC, authorized to regulate "all interstate and foreign communication by wire or radio" by Congress, most assuredly is supposed to have the authority to ensure Internet Service Providers cannot arbitrarily block some websites to subscribers. Whether it really has the power or not is determined by courts - and the courts are massively swayed by the arguments of Comcast, related trade associations, and powerful organizations like the US Chamber of Commerce. So long as Comcast and other massive corporations own the infrastructure, they will make the rules. We can attempt to fiddle at the edges by responding via the FCC, or we can build public infrastructure (over which they can provide services without making the rules) and avoid this entire problem.
On this particular issue, though, I found the following bits helpful in understanding the decision and how it changes federal policy.
Cecilia Kang of the Washington Post posted a
video interview with Ben Scott of Free Press that is well worth watching to understand what is at stake and what is not. For instance, the FCC is not proposing to regulate the Internet so much as the wires and transmissions that allow the Internet to run. As long as Comcast can decide what bits it wants to transport (as in, it will transport bits from CNN but not Fox News, for instance), the open Internet is at risk.
