And who knows if the analysis that is derivable from this private data leads to a bunch of false-positives (that are conveniently not known by the person affected)?

1984 or Brazil - it doesn't matter they're both dystopias that revolve around totalitarian constructs - neither of them work without this kind of comprehensive information.
