In what way? I agree that personally tracking an individual and using psychology tricks and whatnot to trick them into buying stuff is bad, but if it's just a company knowing what works well for them, I don't see the argument.

> when you go shopping and pay with cash in a store with no surveillance, your shopping habits are being shared against your wishes with a random third party

Retail stores also use your shopping data to target you with ads. Credit cards also obviously sell your purchase data to anyone willing to pay for it. I wouldn't be surprised if retail stores even sell your cash purchase data to any third party willing to pay for it.

Information is valuable, but it is not holy.
