The problem for e.g. Facebook, Reddit and other link aggregation sites is that they have a very non-specific audience - which is fine for e.g. Coca Cola that want everyone to see their ads, but impractical for small advertisers that want to target a specific niche. The promise of the ad networks is that they'll find the niche sites for the advertisers who then don't have to find suitable places to advertise on and buy ad space in a bunch of different places - less administration needed. I don't think that this adds enough value to be worth eroding the privacy of all web users, but apparently it is according to the people who make the decisions. ️:shrug: (Apparently HN strips away emoji from comments, didn't know that.)
