> The worst thing that people can point to that this kind of advertising has caused is fake news on Facebook

The worst thing about targeted ads is that we're building an insane surveillance infrastructure that the government is already eager to tap into, and will be even more eager if one of our governments devolves into dictatorship.

I'm from East Germany; and while I'm too young to have experienced it myself, the Stasi is still fresh in our minds. What we build today in the name of improved advertisement would have brought tears to Mielke's eyes.
