Some mistake or miscommunication happened there, as Wikipedia does have a policy that people can be cited for information about themselves, the policy is called SELFSOURCE. See: https://en.wikipedia.org/wiki/WP:SELFSOURCE

Perhaps the issue was that Philip Roth was unable to sufficiently demonstrate his identity? Of course, Wikipedia can't take a random editor's word when they say "I am this person and this is the truth", then anyone could say anything. There has to be some citation, for example I've seen someone cite a tweet for simple biographical information (e.g. "today is my birthday").
