Most of the arguments here circle around "ah you were a fool to let your data out, so Google was wise and snooped it". WTF kind argument is that? Since when is it ok for a corporation to hire "experts" who go around collecting private data? What is this data for? Why, in the first place, do they have a wifi expert driving around doing that?
To mark hotspots you don't need packet sniffing or data capture of any kind. Why is Google capturing packet payload during "wardriving"? Nobody does that. All you do is store the GPS location, plus basic AP identification, period.
How do you know if an open wifi is a corp network that just enforces VPNs to actually do anything?
If they connected to the AP and ran nmap against my server yes it would be like that... but simply capturing packets that are broadcast into a public space I don't think is reasonable or realistic to expect it is some grave violation of privacy.
I don't think I will close my ears at any point.
Yeah, if it was only near your home. But if you went around driving and listening to hundreds of "loud neighbors" for a day that'd change from passive listening to being outright creepy.
I don't think it benefits anyone to argue against the analogy, rather than arguing against the reality in this case.
I do find street view creepy.
At what point do you pass the creepy threshold?
