Other side of the same coin: I work for a municipality, and I can’t even connect my phone to the intranet because they use MAC whitelists for the entire network. The only thing non-whitelisted devices can even connect to is the (really shitty) public WiFi. Many cities used to be pretty lax about cybersecurity, but a few high profile attacks have made most of them (at least anything larger than a small town) rethink that stance. Hell, one city a few miles away had a ransomware attack that left their city services entirely unavailable for like three weeks. That was actually studied by lots of the local cities, to see what they can do to prevent similar attacks.
I hope that's not the only thing they do. MAC addresses are easily spoofed.
