The 451 code (which, by the way, is a reference to Bradbury's Fahrenheit 451, not Orwell's 1984) just says that a resource is "unavailable for legal reasons". These "legal reasons" may be user-hostile (e.g., censorship) or user-friendly (e.g., GDPR). Having said that, it's just good form to specify why exactly a request was denied rather than spitting out an "access denied" response and call it a day. Be liberal in what you receive, conservative in what you send, yada yada.
