Does censorship by religion make things better or worse?
Of course they make things worse. Not to mention how they give publicity and mistique to whatever they are censoring. E.g., Satanic Verses was a good book, but it wouldn’t have been nearly as popular if the Iranian government hadn’t put Rushdie on a death list. That’s one of the reasons the Catholic Church stopped issuing its “Index” of censored books. My grandmother said that “God’s Little Acre” was a mediocre, mildly amusing book, but once Rome put it on its list of forbidden books, everybody and their godparents read it.
