TLS 1.3 is just a protocol for transporting encrypting communications. We have had such protocols for a long time. Censorship has continued unabated. There is no technical solution that can prevent censorship. Censorship is a social issue. If a government policy, or the policy of a privately held corporation, insists on censoring something, it will do so. Literally the only way a transport protocol could end censorship is if a law were enacted that specifically stated "This protocol may not be circumvented or obstructed by any party, private or public, by any means, for the purpose of censorship.".
