Heard a similar story on the radio this weekend, and found it such a lightbulb moment that I thought it was worth passing along:

If you travel a fair bit, as I do, you’ve noticed at almost every airport that there’s an “ad hoc” (i.e., computer-to-computer rather than computer-to-WiFi) option called “Free Public WiFi.” It seems to be everywhere. I’ve never connected to it, because I know enough not to connect to an ad hoc offering, but I was always amazed at the fact that I see it in pretty much every airport I’ve been to. I had wondered if it was a honeypot scam for a while, but I couldn’t believe that scammers would be able to set up such honeypots in so many airports worldwide and no one would catch them and take it down. So how could there be such “Free Public WiFi” (which obviously was not what it claimed to be) in so many places?

The answer? Well, it’s all Microsoft’s fault.
