WiFi passwords aren't about security for the people using the network, they're about blocking people who haven't paid for it. If, as an attacker, one of your targets is using JFK's airport WiFi, getting the password for that WiFi is the least of your problems.
Whether it's ethical to hand out passwords to people who haven't paid for WiFi is another question entirely, but wouldn't it be sweet if businesses just let anyone join their WiFi? Bike repair shops always leave a pump outside for anyone to use, not just customers.
