Can we all just calm down and take a sensible look at the risk. Is for example, the risk of getting hit by a meteor, bigger than say getting legal attention for having an open wifi? Security researcher like Bruce Schneier keeps an open wifi, and he argues this exact point. ( https://www.schneier.com/blog/archives/2008/01/my_open_wirel... ) There are also plenty of solutions if one want to eliminate this "risk". Hook…
1) slow it down
2) cost me money if I do not want 1) to happen
You know, I do not travel to volcanoes, but I do use the Internet. And being hit by a meteor is something over which I have no control... My wifi is completely mine to tinker with.
On the other hand: and I am not into risking SO MUCH (just the fact of receiving a letter is too much for me, sorry my values are not equal to yours) for so little benefit, sorry.
It is a risk without quotes, it is probably not a "danger" from your point of view (just to be precise): risk is anything with a potential damaging outcome... Yes, any activity is a risk. Just ask any insurance company out there.
And frankly I could not care less about Schneier's open wifi and his arguments in this case.
