How is that different from e.g. cars? The roads are a public good as well, not?

It’s generally accepted that reporting on car movements is allowed as well. You don’t have a right to privacy of movement on public roads.

Transponders are in planes mostly for safety. Their automated dissemination is part of the safety mechanisms of that transport medium and putting up with them (when required) is part of the privilege of using that public good. Similar to requiring drivers licenses to drive.

This is certainly not true in Europe, and in the US there's generally zero restrictions on publicly sharing any kind of PII.

For one thing, it's different because there is no law that cars need an active transponder while operating.

But cars do have a license plate anyone is free to look at while they drive by so in that sense it's the same.

Isn't it pretty established in the US that e.g. companies selling bulk license plate scanner data is completely legal, and any "right to privacy" isn't really a thing in public space? (very different in other parts of the world, but US seems to be the relevant context here)
