Anyone else notice that privacy control settings are kind of fake?

I was thinking about this the other day. When companies allow users to stop sharing data for personalized ads, tracking, etc, the companies do not display them to the users, but (probably) continue to collect the data and exploit it.

For instance, Walmart has a privacy setting that allows users to not add in-store past purchases to the account based on payment method. If the user turns this setting off, the user won't see in-store purchases in the purchase history. …
