Privacy in the aggregate vs. Individual privacy (Score 1)

The aim of these privacy busting programs is to facilitate sharing of information. It happens that I like cinnamon, and I routinely order it online from a company that imports a very good product from Vietnam. It does not harm me at all that the data involved with my orders are collected and collated with other data. Eventually, someone may discover that because I like other things, I am probably interested in cinnamon, and if some company has a better price for the same quality, or better quality, period, I will benefit from knowing about it.

What is worrisome is the collatoral ability to create an individual profile from the available data can result in someone finding out not only my shopping habits, but my bank balance and whether or not I like to look at pictures of naked teenagers peeing on each other.
