That's false. Musk's jet is not enrolled in PIA, which is just a programme that obfuscates the ADS-B identifier from the FAA's registry. Spotters can still find the aircraft. However as I said it's not true in this case, the FAA registry entry for the aircraft has the accurate ADS-B hex code identifier, and the aircraft is trackable openly on sites like ADSB Exchange and even using your own ~$20 hardware radio receiver. Sweeney is doing nothing out of the ordinary for this particular aircraft other than linking the ADSB Exchange API to a Twitter account. As an aside, there's also nothing illegal nor morally wrong about spotters deobfuscating a jet that's in the PIA programme either. That's just a fig leaf measure, it's not actually effective.
