"Net neutrality"  is, according to Wikipedia, is where all the sites and information is treated the same...where they don't 'discriminate or charge differently by user, content, website, platform, application, type of attached equipment, or method of communication.'

It's an Obama-era rule that guaranteed equal access to the internet.

In December of 2017, the FCC voted to repeal net neutrality in the United States.

According to the Associated Press, Maine's U.S. senators say they are getting behind an effort to restore "net neutrality" rules. Republican Sen. Susan Collins and independent Sen. Angus King say they support a bipartisan Congressional Review Act resolution to bring back net neutrality.  Collins and King say in a joint statement that protections under net neutrality have allowed businesses in Maine and elsewhere to have equal access to the Internet so they can "innovate, grow and compete in the global economy."

There have been other legal moves by some states filed against the FCC to fight this move.
