It’s true that census confidentiality is imperfect and could be used to compromise civil liberties, but I can’t imagine any way that it could be used to steal one’s identity (especially if one is cautious enough not to provide name information on the form). IRS, that’s a different matter. Anyway, Equifax has found another way to sell their protection racket. If it’s “only $4.95” for the first month, how much is it thereafter?
