Marketing is fundamentally aimed at changing people's opinions. This can be done 1. covertly (why do you need to do it covertly? Would people mind if they knew? Doesn't that indicate you're doing them a disservice?) 2. overtly, against people's will. (Again, doesn't that indicate you're doing them a disservice?) 3. overtly, with their consent (express or assumed). How often have you seen this happen? The "indicates" vs "shows" distinction above deals with the edge case of "interacting with covert/unwanted marketing is actually good for them, even if they don't know it". I dare you to make that argument...
