Technically, most companies in the advertising space don't sell user data. They sell the ability to target users based on anonymized and pre-digested data. Google Search Ads and AdWords both work that way, as does pretty much all of Facebook's ads products.

As an example, Facebook might sell you the ability to target people between ages 12 and 20 located in major metropolitan centers in the US. You never bought any user data that let you flag individual users, but you are still "using" the data.
