Critics of the rules say they still interfere unnecessarily with ISPs' ability to ease congestion and develop new revenue streams. Meeting the ever-growing demand for bandwidth is expensive, and if ISPs can't charge content and service providers, they'll raise prices. Some also argue that the uncertainty caused by the rules will deter investment in broadband pipes.
Supporters counter that technological advances are steadily lowering the cost of supplying bandwidth. If ISPs are allowed to charge sites or services to deliver their data — for instance, by creating "fast lanes" on their networks that take priority over other traffic — upstarts, innovators and noncommercial users will have trouble competing with major brands, Hollywood studios and other deep-pocketed interests.
In essence, the debate boils down to a question of what freedom online is most worth preserving: the freedom from regulation, or the freedom from interference by ISPs.
Where does the situation stand?
Congressional Republicans, who've made it a priority to repeal regulations adopted by the Obama administration, are trying to overturn the FCC's action through a legislative technique known as a resolution of disapproval. The House passed such a resolution in April on a largely party-line vote; the Senate is next. However, even if it attracts enough Democratic votes to pass, it's likely to be vetoed by President Obama, who advocated net neutrality in his 2008 campaign.
