The court decisions focused on peoples ability to be part of society, and as far as I know that US prison system is the opposite of that. If in the future the prison system was reformed to be rehabilitation rather then retribution, then question like how inmates can access the real internet become really interesting. To quote: "convicted criminals—might receive legitimate benefits from these means [social media] for access to the world of ideas, in particular if they seek to reform and to pursue lawful and rewarding lives."
