A major issue this does not consider is that ads which are too accurate are often deemed 'creepy'. Turns out there was some recent research on this topic [1]. In another thread on digital advertising a user shared an anecdote of a company that met with poor response after targeting locals who were pregnant with new baby related promotions. But after masking the promotion in a packet of otherwise unrelated offers, it met with much better results. Another thing here is that this information isn't going anywhere. All the information that you give up to companies can be exploited at their whim and to whatever end they choose. In this regard I think Cambridge Analytica was a really great thing. They were, all things considered, probably a very small player. But for people to realize that their personal information could be used for more than to try to sell them crap was an important lesson. There are also things like the NSA who are now hoovering up immense amounts of information, facilitated by participating companies including Apple, Microsoft, and Google. Recent issues should show the problem here. The NSA is not immune to hiring people they should not (from their perspective) hire. Their secret tools get leaked. They themselves get hacked. And now there is this immense trove of potentially sensitive information that they're sitting on. That data is going to eventually end up in the wrong hands. It's also not out of the question that the NSA themselves eventually end up being the wrong hands. Without invoking Godwin's law here, it should suffice to say that bad people can get into positions of power and do very bad things. Pair this with profiles on everybody in the nation, and increasingly even the world, and it opens the door to some really catastrophic scenarios in the future. So no, don't forget privacy.
