Having a URIBL that hits some ham means that I may, as with other rules, have to whitelist more senders. OTOH, not having one means that users will receive more spam, which is complained about far more here than FPs.
The problem with FPs is that they may prevent a message from ever arriving. Absent a telephone call or some other communication, a falsely blocked legitimate message may never get discovered. FPs are far more damaging than false negatives (spam that gets through undetected). Therefore it's much better to get a little spam than to get legitimate messages blocked.
My goal is to eliminate spam. Part of my strategy involves quarantining. BLs such as UC allow me to quarantine "possible spam" through scoring or other mechanisms. Don't blame the DNSBL if people use a quarantine-only list for delivery-time rejection.
