The analogy that's sometimes used is that of a safe full of documents. Current case law says that you can be compelled to turn over a key but cannot be compelled to turn over a password [1]. The Department of Justice is saying that a fingerprint is more like a key than a password I guess. Or alternatively that unlocking phones is search and not testimony. The EFF seems to be primarily objecting on the grounds that a search of "all devices in the building" is too vague to be a correct warrant.
