While Tuesday's ruling handed Trump-appointed regulators a partial victory, consumer advocates and other groups viewed the ruling as a victory for states and local governments seeking to put in their own net neutrality rules.
The FCC's 2015 net neutrality rules had barred internet providers such as AT&T, Comcast and Verizon from blocking, slowing down or charging internet companies to favor some sites or apps over others.
After the FCC repealed the rules, phone and cable companies are permitted to slow down or block services they don't like or happen to be in competition with. Companies could also charge higher fees of rivals and make them pay for higher transmission speeds.
Such things have happened before. In 2007, for example, The Associated Press found that Comcast was blocking or throttling some file-sharing. And AT&T blocked Skype and other internet calling services on the iPhone until 2009.
