The plan Wheeler proposed earlier this year would not rely on that authority, but would instead allow for companies to make “commercially reasonable” deals to speed up users’ service on a particular website. Critics have said that would lead to “fast lanes” on the Internet, with quicker speeds for wealthy companies and slower service everywhere else.Supporters of strong rules have told the FCC that the stronger legal backing is the best way to prevent companies from slowing users’ service or blocking their access to particular websites.Critics, however, have said that the rules were designed for telephone monopolies and would lead to utility-style regulation on the Internet. In their comments to the FCC, cable companies have said that reclassifying broadband service to use the tough rules would likely be a violation of the law, which could tie the new rules up in court for years to come.
