Then the people who abuse the demographics see a amazing opportunity, they are the only ones who can differentiate the distorted and real data.
So they can use their unique knowledge to put themselves ahead of the game.

Anyway, who cares if some company knows i like mint ice cream.
Or that I like to go jogging from 4pm - 7pm.
As long as they dont bug my bathroom and take pictures of me in the shower I really don't care.
Actually it would be quite nice to have products that suit me a bit more than ones on the market already.
Whats the big deal?
I already disclose a huge amount of information about myself to colleges, friends and partners so why should I go all ape shit when somebody tries to find out whether people in my village like tea or coffe.
