My point is that it would be much harder to know which airplane is Elon's jet if it weren't for the twitter account.
Which goes to the gp's point that even if the data is public, making it easily accessible increases Elon's personal safety risk.
That said, the NYT story does seem to make my point a bit moot. In any case, I wasn't aware of that story, and it didn't come up when I searched for "Elon Musk jet callsign".
Although I would guess a determined attacker could find it out given sufficient research.

You don't have to be determined; a college freshman on a lark found Musk, Gates, etc. and made Twitter accounts. This information is intentionally public; you can browse recent plane registrations at https://registry.faa.gov/aircraftinquiry/Search/RecentRegist..., export it to CSV, with full name and address of each owner.
I get a text message whenever my dad is seen in the air.
@elonjet isn't the problem here. (IMO, there isn't a problem.)
I've searched for "Elon Musk jet callsign" but apart from the mentioned twitter account, I couldn't easily find out which one it was.
