via SCOTUS Blog:

In a 6-3 ruling, the Court decided that cable operators offering high-speed Internet access have no legal duty to open their service to customers of all Internet service providers.

In the cable case, the Court upheld the decision of the Federal Communications Commission that broadband cable moden companires arfe exempt from mandatory common-carfrier regulation. That, Thomas wrote, is a lawful interpretation of the Communications Act, and thus is due deference.

Public Knowledge is first out of the gate with a statement from their president, Gigi Sohn:

The Court's decision today raises the question of whether Congress, in tackling its next revision of the Telecommunications Act, should act to ensure that communications, content, and applications are allowed to pass freely over the Internet's broadband pipes. We believe Congress should do so, because "net neutrality" is a worthy goal that not only will promote free speech and creativity on the Internet, but also will benefit those who provide broadband connectivity by making that connectivity more valuable.
