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.
