I read that a man has been arrested for using an unsecured wifi connection.
I've often wondered if you can piggy back on someones wifi and apparently it has been illegal since 2003. Some people seem to take the view that if you don't secure your network then tough, whereas other take the view that an open door wouldn't give you the right to go in to someones house and "borrow" some water.
It leads though to an interesting discord on what is theft. As was pointed out on the BBC site many of us will happily walk off with a biro from a bank or office and not think about it whereas we wouldn't do the same with a Silver Mont Blanc Pen.
I suppose the view is that if something has no intrinsic value we don't worry about it. The truth is I guess that someone elses wifi connection is theres and "borrowing" there internet is still theft. Then again there are unsecured networks (like Cloud) where you can buy time so how do you know?
But that said if I had a wifi network I'd secure it in the same way I wouldn't leave my front door unlocked.
