The modern English sense of “censor”, IIRC, isn't directly derived from the as actions of the Roman official, but more from those of the Catholic ecclesiastical official of the same name (sometimes more fully “censor librorum”) who reviews books intended for publication and provides (or withholds) the nihil obstat certifying it free of anything harmful to good faith and morals, which is generally a prerequisite to the episcopal imprimatur allowing it to be published, a function which is very much in line with the modern English understanding of censorship.
