reference Goebbels: "I have nothing to hide, so I'm not worried"
Downplay: "They only read my emails and everything I write to sell me stuff better. Sometimes I need stuff. They're helping me!" As if it can only be used to sell and nothing else.
World revolves around self: "Well ads don't affect me." Like it doesn't matter that everyone else is affected even if you aren't.
Completely ignoring the fact that if someone can manipulate you to buy stuff they might be able to use it to manipulate you do do other things. I mean we have political ads. And Coke ads aren't there to sell you coke (they are there to make you feel better about your purchase). Frankly, to me it doesn't even matter if no one has done that yet (I'm aware of the clear evidence that people have) but that we're giving people the ability to do this in mass and in very precise ways. That just leads to a potential turn in democracy. "Just educating people" doesn't solve the problem either. Ads are still effective on smart people. So the question is "are the benefits ~~profits~~ worth the cost?" It is reasonable to think "yes", but I'm a resounding "no."
Yes, we use political ads to "manipulate democracy" and the like, but a mass statewide commercial is a very different thing than an individualized ad targeted to a specific person. At least to me these are very different (and we still have regulations on what you can say in political ads). Where do we draw the line? We talk about data a lot here and what we can model with it. What will ads look like in 20-50 years if we don't draw a line in privacy and technology continues to become more powerful? I think individualized ads will look very different. We do need to determine what level of individualization we can target with an ad, and I don't see much of that happening.
