That's a completely different category of life violation though. Imagine instead that your bank was lying to you about your account balance, modifying it to be plus or minus 3% of the actual balance. Without your consent or knowledge. All to conduct a "psychology/market experiment".

Then it would be equivalent.

Nothing in this post involved distortion of customer data. They just linked up transcation time/date and geo-location data. Then did some simple math. It's not out of the question that your payment processor could replicate this analysis...Once your credit card processor cuts a deal to geo-tag your purchase history. Of course almost all fixed POS hardware is geomapped, and the mobile stuff is trackavle, so that's not much of a stretch.
