The FCC believes such regulation is necessary to protect consumers. Without such regulation, many argue, internet service providers would be able to regulate the speed of transfer of packets of information in such a way that it would create a tiered internet-- how much you pay determines how fast your 'net is, and if a company doesn't pay the right ISP, their website might be slightly... sluggish.
Not everyone agrees. Comcast is worried that the proposal, which will likely take a better part of a year to lead to any new regulatory policy, will "ultimately `open` the door to the entire heavy burden of regulation," so says Joseph Waz, Comcast's senior VP for external affairs. Many other broadband providers, including AT&T, concur.
Google, while not an ISP itself, is influential in their support of net neutrality and is the founder of the Open Internet Coalition, a lobbying group founded to promote open access. They're playing this controversy a bit mercenary. While not coming out in open support of the move to reclassify broadband networks, Rick Whitt, on Google's public policy blog, said that "we support whatever jurisidictional fix is most sustainable legally" to keep the internet neutral.
The FCC v. Comcast decision has likely opened up the door for future litigation to protect the internet from federal regulation, and this move to reclassify the internet will be met with strong opposition. The next few months will provide time for the government to decide exactly what powers, if any, the FCC has to regulate internet service.
