>Ad tech has been around since before the internet.

True, but it was never this granular on this mass of a scale. I remember joking as a kid about the Nielson families that would kill a TV show because they went out to dinner instead of watching TV that night. The extrapolation that was applied to those kinds of numbers were always ripe for bad interpretation. The same thing can be said about polling numbers. The granularity is what makes modern day "ad tech" or tracking in general so damn dangerous in its accuracy

Every loyalty card purchase generates granular data about your consumer habits. Where you shop, what you buy, how much you spend. Coupled with age, income, race, sexual preference, political affiliation, and more makes for a deep insight into your inner life. These businesses don't operate out in the open so the general public is mostly ignorant about what has been going on. The level of invasiveness that has existed for 30+ years should not be underestimated.

It's only about you if you actually provided accurate information. I've never signed up with legit name, age, sex, phone, address with any system of loyalty payments. most of the time you can enter some random phone number and it'll work. so now you're just skewing someone else's metrics. there's all sorts of ways to get the store's "member" pricing without submitting your life to them

They can correlate with your CC identity for electronic payments. Unless you always pay with cash you're being tracked.
