Why do most celebrity writers despise being interviewed?

Most celebrities despise being interviewed because they see it as unwanted interference in their private lives. Many people like V.S. Naipaul are of the view that their feelings are wounded by interviews while Rudyard Kipling’s wife, Caroline, called interviews “Crime” “Assault” “Cowardly” and on the other hand Lewis Carroll was claimed to have ‘a just horror of the interviewer’.
