They are banned though. Not curated. You are not allowed to have these in school libraries. It’s not an editorial decision. For instance the Utah law says that a book must be removed from all libraries if 3 school districts in the state ban it.

No librarian, or teacher, or admin or parent in the other school districts gets any say.

That’s a ban. People may not like that their state is engaging in authoritarian behavior, and it’s less authoritarian than other behaviors, but it’s a ban by the simple facts. Doublespeak doesn’t change that.
