Well, I do limit my "sugar" intake.
It’s close to zero and limited to when I’m on the go and there is no candy store in sight.

And apparently the known viruses fail to bite on my Apple. :cool:

People with those intentions don't even have to infect the datastream. They only need to watch for your plaintext email/chat/blog login names and passwords. As far as the "ooo, I got free wifi!" freeloader is concerned, they got away with it.

I never attach to hotspots listed as "Computer to Computer" under the Airport menu. Way too many reports of laptop owners turning on sharing and naming their computer "Free Wireless" with the intention of becoming your Man in the Middle. There was another article a while back about how often "Evil Twin" traps are set up.

Did you get away with free wifi, or did free wifi get away with your online identities?

When I was a kid, I had a very long walk home from school if I took the sidewalk. I could cross a few yards and save some steps. I only crossed the yards with no fences, that seemed fair game and still seems so. I never jumped over fences, even low ones that I could have jumped.

I see open wi-fi exactly the same way. If you don't want me to cross your yard, put up a fence or even a sign.

ArsTechnica has weighed in on this question: "The ethics of "stealing" a WiFi connection". They don't think it's unethical.
