  "rationale": "CTIA expects exactly one confirmation after STOP, and a subscriber who receives it without warning reads it as the opt-out having failed — which is the most common trigger for a complaint filed immediately after someone has successfully unsubscribed. One sentence in the terms turns that message from evidence of a broken system into evidence of a working one.",
