You're giving the average user too much credit. As a software developer lurking on Hacker News, sure, you understand how pervasive tracking and data collection are. But have you spoken to your parents or older relatives? My mom had no idea that kind of stuff was even possible. Most of those people still think that the core invasion of privacy us tech nerds are always going on about is the public content (the likes/follows/posts). I'm not patronizing, they genuinely don't understand the scale of modern online tracking.
