I assume they are referring to the blocklist described here: https://www.faa.gov/pilots/ladd

> ADS-B Out transmits flight data directly from the aircraft to internet vendors not participating in the LADD program. Non-participating internet vendors collect and post all ADS-B Out flight data on the internet. To address ADS-B Out privacy concerns, the FAA has initiated the Privacy ICAO Address (PIA) program to improve the privacy of eligible aircraft.

ADSBExchange does not participate in the program that the blocklist is part of. They even cover this on their homepage

https://www.adsbexchange.com/

> First and foremost ADS-B Exchange does not participate in the filtering performed by most other flight tracking websites which do not share data on military or certain private aircraft. Because ADS-B Exchange does not use any FAA data there are no FAA BARR/LADD, military, or other “filters” preventing you from seeing the the data you collected. ADS-B Exchange simply does not accept payment or requests to remove aircraft from public tracking!
