The sitcom Rosanne was removed from my Apple library purchases after the actress went on a racist tirade. Was it banned by the government? No, but my access to the material was taken away. I think that there is censorship beyond government censorship, especially when competition is limited, as it typically is with art under copyright (as well as payment processors, etc).
If you lost previous purchases, that sounds like an account question between you and Apple. Other than your anecdote here I don't see complaints come up in web searches that they removed it from people's libraries.
