Because the court case wasn't even about content on the internet but the regulations they put in place for internet service providers. You know, like the fact that if you advertise that your package comes with 5GPS download speed, you actually have to provide 5GPS download speed for people who buy said package? That's the type of thing that the FCC was doing, upholding existing laws in a field which is new, and only because it is new are there no laws technically in place to govern it (though at the same time they also are technically under the FCCs mandate given the wording of the laws are open to interpretation). Net Neutrality, and it being eliminated in a lower federal court, was never about the content of the internet nor the threat or possibility of it being censored, it was and is about the laws and ethics around the service being provided.
