Under the current rules, broadband internet is a Title II service, which means it's classified as a utility and ISPs are required to treat all data equally. It's what prevents throttling based on content, blocking of legal content and services, as well as paid prioritization. The FCC's proposed rollback would reclassify broadband as a Title I service, which has much fewer regulations. A lot of creators would be greatly disadvantaged by the removal of Title II protections, the letter says, since it means ISPs can prioritize connections to media companies that can afford to pay for it:

"These regulatory changes will give ISPs immense influence over how we as creators can connect with each other and our audiences. If real Title II net neutrality is lost, we will lose the permissionless innovation that has made creativity on the Internet so great. Internet providers will have new influence over how we as creators can connect with each other and our audiences, which will have major implications for the diversity of voices available online."

The creators stress that the rollback could affect all creators, no matter how many subscribers they have. In fact, the letter was signed by some of YouTube's biggest stars, including Joe Bereta, half of the web sketch comedy duo Barats and Bereta, who has over 30 million subscribers. Benny Fine (20 million subscribers) of Fine Brothers Entertainment, known for the REACT series, also signed the letter, along with Dane Boedigheimer of Annoying Orange (15 million) and Ned Fulmer of BuzzFeed video (12.6 million).

The open letter says the creators will "fight for as long as it takes." It also encourages people to participate in the July 12th "Internet-Wide Day of Action to Save Net Neutrality." Their success depends on whether the FCC and the government will listen to their arguments, though, because the agency has made it clear long ago that it doesn't care what we think.
