If you are sure of yourself, do a little experiment. If you truly believe it’s legitimate, why not just buy an AirTag and hide it on a person’s car…perhaps a local well known business owner. Create a website that publishes the live location of the vehicle. Let us know here how that goes for you.
The simple fact of the matter is that due to how this data is created, it's publicly accessible information: All airplanes flying in civilian airspace are required to broadcast ADS-B data for safety reasons. It gives controllers (and other aircraft in your nearby airspace) a view of what's happening. Your airplane essentially broadcasts a payload every second that sends out your GPS coordinates, heading, speed, altitude, aircraft identification information, etc.
The COOL thing (speaking as an aviation geek), is that you can buy a cheap little antenna, plug it into a Raspberry Pi and start seeing these raw packets from airplanes FLYING OVER YOUR HOUSE. FlightRadar24 and ADSB Exchange basically crowd source a bunch of real-time data from people who have these antennas and are running various types of software.
Basically, since this is happening in public view and the data is available (primarily for safety reasons), then there is really no reasonable expectation of privacy. In a way, it's like people taking a photo of you on the street and posting about it -- since you're in a public space, there is no expectation of privacy. You might not like it, morally it might feel wrong, but there is no reasonable legal reason that bans this.
Fortunately (for Elon), he is a billionaire and can lobby to change laws he doesn't like if he so wishes.
Also I should note, that nobody asked me if I think people who intentionally cyberstalk folks online using public information are slimy either…(but I do).
If you have an objection to this tracking, you'd have to take it up with the FAA. Because the legitimate interest is that the rules require airplanes to transmit this information any anyone is free to listen to it.
Which is a great thing for aviation safety, so I'm glad the rules exist.

Just exactly what “responsibilities” do you perceive me to have in this discussion? Others are advocating monitoring another person’s property using technology and publishing it on the internet. I am suggesting that there is no reasonable civil reason to do so. The only “responsibility” I have here is to be true to my opinion. I stand by it.
Also, I used the term “cyberstalking” because that is exactly what it is. Here is a Wikipedia page on the term:
https://en.m.wikipedia.org/wiki/Cyberstalking
According to that page cyberstalking is the use of the internet and technology to stalk an individual and those actions “may include monitoring”.
Here is the definition of “stalk”:
https://en.m.wikipedia.org/wiki/Stalking
“Stalking is unwanted and/or repeated surveillance by an individual or group toward another person”
If you find fault in my definition, feel free to push an edit to those Wikipedia pages.
I mean, that particular individual is in turn weird and not okay.
But who am I to say? And what does it matter if something is weird and not okay? Lots of things fit that bill, and that doesn't mean they shouldn't exist.
I don’t question the legal right to use this data this way, although I think good arguments could be made that if you are using the data this way, your intention is suspicious and you invite scrutiny. I am challenging the folks commenting here that the data being used this way is a positive use of the data.
