It seems that nobody ever considers the other side, which would be that people are now targeted with ads that they want to see instead of poorly targeted ads that just waste their time. Another plus is that small advertisers can now afford to advertise alongside companies with much larger budgets by micro-targeting. I've engaged with lots of ads on Facebook and its not because I'm stupid, it's because they are showing me things I'm interested in. There's nothing wrong with being concerned with how data is being used but this constant dialogue from the "never ads" crowd is pretty tired.
