Worth pointing out that the prior status quo of a library collection was not apolitical. A library collection, especially a school library collection, is always guided by certain ideological priorities. There's only so much money to buy new books and replace old books and only so much library capacity to keep books. It's a zero sum game where some books get selected and a lot of others get rejected, and how those decisions get made have always been guided by various ideas, policies, and values.
A huge part of a librarian's job is curating the collection, deciding which books get bought or not, which books get space on the active catalog vs going into deep storage or the dumpster.
That said, this sounds more like an organizational screw up than any intentional ideologically driven outcome. We know what the latter looks like, it's happening all across the US and the people advocating for empty libraries aren't shy about it.
I could easily see librarians being faced with a huge work request, like a sweeping change in curation policy, and not having time and resources to do it properly, resulting in what we see here. Wouldn't be the first time upper management has made impossible requests.
