Through The Internet Association, Twitter has joined other leading Internet companies to urge the FCC to promulgate common sense net neutrality rules. FCC Chairman Tom Wheeler has proposed securing the legal foundation for these rules in Title II of the Communications Act (along with other statutory authority). We strongly support ensuring that such rules include prohibitions against blocking or throttling of sites and services as well as the paid prioritization of some traffic over others. These rules should govern Internet service whether users are at their desk at home or on their smartphone across town.
