Flight tracking vendors that use FAA data are required by law to comply with LADD. Ones that run their own ADS-B networks and use no FAA data (e.g. ADSBexchange.com) are not.

Note also that FlightRadar24 and other ADS-B vendors are required by law to comply with FAA LADD, so airplane operators can request (demand, really) their information be scrubbed.
