The 539-page Restoring Internet Freedom Order comes about three weeks after the agency voted 3-2 along party lines to dismantle rules passed in 2015 to ensure that all traffic on the internet is treated equally and to prevent broadband and wireless providers from blocking or slowing online content. The agency also voted to eliminate the legal foundation that gives the FCC oversight of internet service providers.

Even though many people agreed with the basic premise of net neutrality, the FCC's rules became a lightning rod for controversy because they placed broadband providers under the same strict regulations that govern telephone networks.
