It would appear that Larry Page and Mark Zuckerberg were right on a scale I
didn't realize: people as a whole don't place any value on privacy, even in
the information security realm.
I've ordered items from Amazon and thus have an account there. But their
information on me is not complete, lacking (for example) any connection with
information security. Were I to download this book that would be an
additional item in their database about me.
The reason I'm posting isn't to claim that the price is excessive, that
Amazon is evil, that the book should not have been made available in this
fashion, or anything of the sort. What I'm trying to point out is that
people are making decisions based on value judgements whether they realize
this or not.
There is a difference between something being public and it being
correlated. What that difference amounts to is a personal evaluation in a
particular context. And it doesn't have to be as distinct of a correlation
as my case for it to have value.
And I find it ironic that a posting to an information security list about
the irony of giving up personal data in return for a 'free' book on data
privacy falls flat for many people.
(That doesn't mean those people are wrong, it means they fall into the group
whose valuation of the data provided approaches zero category.)
