I remember the first time I saw that in an airport, it was right after I got a laptop and went on a trip, I don't remember where, I just remember that most airports had only just begun offering wifi (not free) and there was of course talk of airplanes getting outfitted (though it didn't end up happening for a number of years), anyway I tried connected to the official "BOINGO" network, only to discover, much to my chargin that it required money, which I didn't have, so then i tried to connect to anything else in the airport, and the free wifi thing was the next option... I of course knew nothing about web security at that point...
