Whoever did that deserves a few years in prison. Normally I'm not too much of a friend of draconian BS - but accurate reports of temperature, air pressure and wind speed are incredibly important for the safety of air travel.
It's bad enough when such systems fail due to whatever sort of issue, but the last thing aviation needs is people intentionally blowing holes into the swiss cheese security model -.-
Also bad if such crucial information is based on a single sensor with barely any physical security
This logic is how we ended up with TSA.
"What do you mean, people used to just walk up to planes with their shoes on and a FULL 8-ounce water bottle in hand with barely any physical security?"
It's easier to stop incentivizing people to ruin the commons, vs. trying to strengthen the commons against all possible adversarial behavior.
