It's not as black and white as you make it out to be on tracking Elon's Jet. There is not one site where this is published (contrary to popular opinion). The data has to be aggregated and the jet initially identified.
There is a very good, objective, article on it here:
Twitter’s decision to ban accounts that tracked private planes, including one tracking its new CEO, has prompted questions about what flight information is publicly available.
www.nbcnews.com
These two sentences pretty much sum it up:
"But other flight-tracking websites, like FightRadar.com and FlightAware.com, do actively suppress flight information about planes whose operators have asked the FAA to block their registration numbers from public view.
However, because ADSBExchange.com doesn't rely on FAA feeds but instead on individual site users, it isn't bound by that program."
ADSBExchange.com - this is a user forum, not a gov public data dump.
So, despite the narrative wanting to be pushed, this isn't "free publicly available data". Someone had to go digging to get it and to publish it.
It is the above facts that have probably prevented someone from backing Mr. Sweeney in a lawsuit targeting Elon. Because lets face it, Elon is a juicy ($$$) target.
