[LINK] More to the world than physics [was: Google's WiFi bungle]

If only physics was the best or only model for understanding the world,
you'd be OK. But it's not, and your shrill protestations and ongoing
category errors prove my point that there is a chasm between the worlds
sides try to understand the other or there will be no end to Internet
mishaps. You're right that lawyers and the like don't fully understand
how IT works. I note that the first stage of this controversy would
have been instructive for non-technologists because it was thought that
Google was only collecting SSIDs and MACs; the question would have been,
are there privacy implications in that? And the educative answer might
well have been no.
But you're wrong to treat concepts like private and public like physical
properties. Yet again, I bring you back to a point of law: the operable
term is "persional information", and not "public" or "private". If a
data set contains information about a person, where their identity is
apparent or can be readily determined, then that data stream is called
"personal information" and it's subject to information privacy law. If
such data was collected and retained without a justifiable primary
purpose and without consent, then the collector has a case to answer.
Collecting (and hanging on to) payload data is very different from
collecting wifi addresses because of the issue of primary purpose. To
go back to your examples of mail servers collecting personal
information, that colelction is intrinsic to how the e-mail system
works, and I wouldn't think it was unjustifiable. But if a mail service
operator then put that personal information to another unrelated
purpose, without informing the individuals concerned, then they may have
breached information privacy law. Which is basically what the Buzz fuss
was all about.
