I mean, there are plenty of negative externalities that this type of gambling brings that are much worse, but at least in this case it does appear that authorities are investigating. At the very least I would expect some law to be broken if interfering with official weather data collection at an active airport.
I agree, but the fact that authorities even have to spend time investigating is a massive negative externality.
A few years years ago, there was no conceivable profit motive for interfering with weather sensors on public property. Now there is one.
