This explanation is untrue. Stealth mode does not limit the amount of
information transmitted nor range of the transmission.

Pilots not in stealth mode get exactly the same collision warnings but
their systems will not report to display devices climb rates and vertical
separation accurately beyond 2Km.

Please read section 3.1.7 of the Flarm Configuration Specification document
FTD-14 before you propagate alarmist nonsense.
