I hope they got rid of the Dead Hooker smell.

think of it this way... open wireless access is akin to letting random people borrow your car.

you don't know what they're going to use it for. they could be robbing a bank, carting dead hookers to the field, drug deals, going through your stuff, whatever... you're basically trusting that the people that use the car are going to do so for good purposes. picking up their kids from school, grocery shopping, running a quick errand, etc.
wifi is kind of the same in the fact that people could be using it to steal movies/music, access nefarious pictures/information, e-stalking, hacking into email/banking accounts, or they could be using it for banking, amazon, videosift, wikipedia... who knows. sure there's logs, but if you know how to access the logs, then you know how to protect yourself and probably aren't concerned with this anyway.

the point is you never know who could be doing what on your open, unprotected access point. if you're willing to fend off the MPAA/RIAA, CEOP, or even perhaps the local police/FBI then by all means, leave your access point wide open. WARdrivers will document your WAP and pirates/hackers/child-exploiters will love you for it.

read the instruction booklet that came with your router. 99% of the time the very first set of instructions after setting the thing up is how to change your admin password and enable encryption. Those instructions are there for a good reason.

Or as a dead hooker transportation system.

Or even drug trafficking.. you could get up to the border, have all your shit hidden in the compartments - they ask to check it, you say "No way man, that's my house. You need a warrant!"

Thank you.

And turns you into a homicidal maniac it seems. No wonder I have all those bodies of dead hookers buried in my back yard....

Stop Lying. These "costs" that the chart refers to are their 5 story homes and 16 fancy cars, whose trunks are filled with drugs. Oh, and dead hookers. We can't forget the dead hookers.
