The old rules paving the way for net neutrality, which governs how Internet service providers treat content flowing through their infrastructures, are officially gone. Starting Monday, a new set of rules passed by the FCC last year take effect . FCC chairman Ajit Pai has long sought to drop the old rules because of their "utility-style regulation." However, the fight over net neutrality isn't over. More than 20 states are suing the FCC over the rules. Meanwhile, Congress is attempting to pass an order to repeal the current rules.
