Let’s play devils advocate for a moment:
Why should I be able to control what someone else knows about me? Seriously? If you sit in a park bench and watch me running around on a hot day I can’t compel you to “forget I was there”. And if you use that knowledge as data to support opening a lemonade stand, and even to reach out to me directly and offer a discount on cold drinks, who is being socially harmed? Where is the “social atomic bomb” here?
And, if I consent to this because you can offer me better prices if I allow you to cookie me, and I don’t see a problem, it seems everything is humming along ethically and harmlessly.
So I’m not sure I buy the conclusion that “behavioral advertising is ethically bankrupt”. Notice in your comment you have to evoke the idea of “mass behavioral knowledge”. What does this mean and how is it bad or different from “minor or regular behavior knowledge”?
Please understand I’m not writing this comment to defend the advertising industry. I’m writing it because I also believe this stuff is potentially grievously detrimental, but I don’t think we have a good foundational construction today for why. And we can’t say what is wrong. If we could, we could more easily point a finger at it, declare it unethical, and make laws against it.
But, no, I don’t think we’ve yet landed on the answer. It’s not some innate “right to be forgotten” and it’s not GDPR telling everyone abstractly that “you can’t use PII in your application”. (The GDPR bit is kinda moot because you argue that it’s unilaterally not okay regardless of consent and the GDPR argues it’s okay with consent, so the GDPR is not a solution to your argument.) There’s something else here to build a case against.
If real harm is impacting individuals or society then shine a light on it! Otherwise it’s just ra ra we hate behavioral advertising because it’s spooky. Which while fun to rally around, doesn't really carry social and legal weight. Pointing this out does not bring me snarky joy, rather it frustrates me because I think we’ll be stuck banging our tech heads trying to make every internet standard and protocol 100% anonymous fighting the digital boogie man until we try a new approach. In order to make social and legal progress, because I do suspect the solution is social and legal, we need a really clear understanding of the problem.
In the face of a globally connected world, what new fundamental right do humans have, that behavioral advertising robs them of, that we must take extreme measures to protect as a society?
