Is he afraid of a stalker following him in a plane? He uses this as an excuse, then discredits himself by going on to threaten legal action against Sweeney. Wants it both ways.
replies(1):
This is of course entirely separate from whether such info was used against Musk or his family, or whether such a possibility is sufficient grounds for attempting to silence those who make it easily accessible (it's still accessible thanks to ADS-B for anyone with basic technical skills and cares enough).
Step 2. Copy one of the tail numbers from the first result: “N628TS, N272BG, N502SX”
Step 3. Paste one of the tail numbers into any one of the flight tracker apps.
If your stalkers can’t even figure that out, you don’t have to worry about them. Otherwise… it’ll take them an extra 45 seconds compared to finding the ElonJet twitter account.
Edit: for bonus points Google “site:faa.gov elon musk registration”. First result is N628TS: https://registry.faa.gov/aircraftinquiry/Search/NNumberResul...

The first blocks it from showing up on sites like flightradar24 which filters out LADD aircraft.
The second makes it so you can't go from tail number to tracking the aircraft once the ICAO has changed and ADSB Exchange doesn't manually update their database of which pseudonymous ICAO numbers are connected to which tail numbers.
All those FAA rules do is mask it in their own public data set that they make available. Anyone with their own data set (aka an SDR at SMO if they’re trying to stalk Musk) like ADSBExchange is not required to mask that data and any law trying force them would run afoul of the first amendment and compromise aviation, since ADS-B makes flight safer for hundreds of thousands of pilots.
However on your second point you seem to be confusing two different things. There's two different systems that you're lumping together as one. The one you're talking about is LADD. Discussed here: https://www.faa.gov/pilots/ladd
FAA even caveats themselves:
> 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.
Now to your point, you're incorrect. PIA, as mentioned in that quote by the FAA, literally changes the aircraft's ICAO number to a new number and delists it from public registries. Using an SDR or the data from ADSB Exchange only gets you that psuedonomynous ID. Once that's changed again you have to stalk someone by following them to the airport and align the takeoff time of when you know they left with the new ICAO number. That's the ethically/morally/legally quesitonable aspect about all of this.
More here on PIA: https://www.faa.gov/air_traffic/technology/equipadsb/privacy
> In order to mitigate these concerns, FAA has initiated the Privacy ICAO aircraft address program with the objective of improving the privacy of aircraft operators in today's ADS-B environment by limiting the extent to which the aircraft can be quickly and easily identified by non-U.S. government entities, while ensuring there is no adverse effect on ATC services.
Maaaybe it’s more ethically/morally questionable [1] but I don’t think it’s a legal issue. Reading more on the PIA, it still require the owner to have their own operational security. Like you said it’s pseudoanonymous and I can’t find any obligations it places on third parties. Nothing stops someone putting a camera on top of their hangar pointed at SMO’s runways and correlate the tail number to ADS-B.
[1] or in this case Musk’s actions on Twitter are less ethically/morally/legally questionable?

That's true, but that falls into the stalking or doxxing category and Twitter already had long standing terms of service statements against doxxing, even before Elon bought Twitter, even if it's not illegal (which I still have open questions about).
I was simply replying to a comment that inferred the only way flight info was useful for a stalker was if you planned on stalking them in another plane... which is obviously incorrect.
Musk can do whatever he wants on twitter and IANAL so what do I know, but between the public interest argument and the public availability of the information, I don’t think Musk has a reasonable expectation of privacy.
That said, anyone using the information to follow him around or harass him is liable to get prosecuted.
