The wifi data was half-in, half-out of their private homes
No, it was out. The Google car never entered their property, and yet was able to capture that information in its entirety. It was wholly out of their home.
No, it was half-in, half-out. By that I mean it was being used in their homes, and "leaked" out because that's what airwaves do. Which isn't typically a big deal, since one hardly expects people to be sitting outside trying to pick it up. That's why this story is such a big deal; this time, someone was. I realize that it [purportedly] was unintentional, which is the only exonerating factor.
You argue that no, the exonerating factor was that Google should have been allowed to do this intentionally if it so desired. That the onus is on the private citizens to encrypt everything just in case someone is out there actively trying to sniff their data. Which is a distinct difference in mentality.
It was meant to be used by them, in their homes
They might have intended for it to only be in use in their home, but they never took the simple necessary technological measure to make it so (encrypting it) which is not a difficult thing to do with a home-use wi-fi router, even for a novice. It just requires them to read the manual.
There's nothing technologically complicated about using a handgun either, and using one could certainly save you from a violent mugging. Whenever you leave your home, there is also a slight chance that it will rain no matter what the weather report says. You might get slammed by a car as you cross the street, therefore you should never leave the house without a pair of clean underwear on, in case you have an unanticipated ambulance ride to the hospital to worry about. And you might run into some tourists from Spain who don't speak English while you're out. Therefore, you should never leave the house without a loaded handgun, a large umbrella, a pair of clean underwear on, and a Spanish-to-English translation dictionary. Otherwise, it's your own damn fault.
and technology had to be specifically modified and sent out in order to intercept it
No, no it didn't. One of the details in this case is that Google basically just used an off-the-shelf piece of software to dump all publicly available information. They caught that data because they didn't customize it.
They were using Kismet, so you're technically correct.
My point, however, remains. Kismet does not come standard, you have to purposely install it - usually to sniff another person's otherwise-private network traffic. If Google's sniffing had been deliberate, my point is that they would have been in the wrong for so doing. You seem to be adopting the position that no, that's perfectly alright, the citizenry had no reasonable expectation of a right to privacy there. That packet sniffing, as deliberate as it usually has to be, is just as easy to do and probably as someone glancing in your window. And that is wrong.
If Google itself had condoned it, there would be little difference between that and seeking to obtain Zero-Day exploits to commercial systems - with the exception that these are private individuals, not mere corporations.
And the fact that there was no security to actually exploit.
I think you missed my point there. I know this is Slashdot, but when I mentioned Zero-Days I was getting at legal exploits, not literal technological ones. Stuff without a lot of case precedent about it yet, such as intercepted wifi data, which Google - if they had done it deliberately, and happily this appears not to be the case - would have been able to take advantage of. In other words, using the fact that technology innovates faster than case precedent is established, to take advantage of people.
With all the hullabaloo from the MPAA and RIAA about ownership rights to for-profit data, we have at least as much right to our data as private citizens
You do. So bloody well tick the little box that says "WEP". Note that's not going to protect you against even the most inept hacker, as its known broken, but Google wouldn't have read your data.
You have now dispensed with a free society's right to have open, unencrypted wifi hotspots in order to support an argument that anybody should be allowed to play Peeping Tom on someone else's data, just because they have the technological ability.
If we tried the same argument with personal defense, society would become an arms race in which everyone had to pack an AK-47 and Kevlar before leaving the house, because any random schmuck could light them up on their way to work. After all, they have no right not to get shot at and taking the appropriate precautions are very technologically simple to learn. They could be taught to our kids in kindergarten.
And I'm pointing out that the point of having a government is to preserve our rights against those who would encroach upon them, precisely so that society doesn't have to become a situation in which the best-armed, or the most-technologically-literate, or the most-anything-else, don't hold the rest of us in sway. The point, in short, is to have a reasonable expectation of a society which upholds our rights and freedoms. So that we don't have to all go out with Kevlar and AK's every day.
Otherwise there's no point to having a government, if it doesn't uphold our rights.
See, I don't really see the "right to run wi-fi without reading the manual" as worthy of government protection.
Hopefully you now understand the point I'm trying to make there, and aren't just trying to avoid hearing it.
