Again, people make mistakes, so they may think the firewall is on, but that one time 3 weeks ago when they were debugging something and they turned off the firewall for it, yeah, we never got around to enabling it again.
Also, my home network is a lot more secure by default than shared public WiFi. At home I have decent control over who and what connects. Sure, people could in theory crack my WiFi password, but the risk of that is low compared to sitting on public WiFi.

Nothing we can do to prevent that, unless we want to turn all laptops into walled gardens. PEBKAC is not the fault of the WiFi network.
