Some years ago (maybe this is still the case for all I know), in England you had to pay to listen to over-the-air TV. The TV police would go around with a van equipped with a radio direction finder, looking for the emissions from television local oscillators, and cross-checking them against a database of paid subscribers.
No subscription... a ticket. No concept of "free radio communications" there!
They still have that in the UK - don’t forget to pay your telly-tax.....
