It really depends on what's in your purchase history, where you live what, job you have, that kind of thing. I certainly wouldn't want to coming out I enjoyed a drink every now and then in Saudi Arabia, and I might want to hide my propensity to smoke cannabis from my boss. Finally there's just the notion that I might not want to be relentlessly marketed to by increasingly sophisticated algorithms, because sometimes it works and people end up buying things they wouldn't otherwise. As these techniques get better I'm sure that will continue to be a problem which only grows, and the data harvested today isn't going anywhere.
