I think it's safe to say that, at this point, most people know that their information is being sucked up. But very few care at all. Some of the people I've spoken with are actually in favor of being tracked because they find it beneficial and they want better ads. I don't know if this is a real desire for them or if they've been brainwashed.

The chance of your personal data being used against you is increasing every day. Leaks are happening all the time; largely from databases presumed to be more secure than an app on your phone. Still, relatively few people are really affected by this.

Please tell me otherwise but it seems that the worst thing the data collecting raised in this post could do is manipulate an algorithm to show you ads or social media content or other website content (most concerning, political propaganda).

That's to say, okay - this is weird but you have to tell people why they should care if you want them to raise concern. WHY is this "terrifying"? I mean, I can speculate but even the worst case scenarios I've told people about have barely raise an eyebrow.
