FCC’s 2017 shift toward permissive call blocking
The FCC moved from treating blocking as risky discrimination to treating it as consumer protection. Carriers were encouraged to stop “obviously bogus” caller IDs and use analytics, even at the risk of occasional false positives.

Set the precedent that networks can police identity, not just carry traffic.
Today’s DNO rule is the permissive era turning into a mandate with enforcement teeth.
