Same here when it comes to how it affects me personally, but I can see how it affects society as a whole (or how it could affect kids) so easily.
Most people don't have an understanding about how their browsing is a part of a positive feedback loop that pushes them into echo chambers on Facebook, Youtube, TikTok, etc. It's a consequence of relying on advertising as a revenue generator for these services. Teaching your kids about how their data is being used for this purpose is important. Sending them raw DNS logs to do that is definitely not going to be effective though.
It's valid to point out to children that platforms have an incentive to suck them in and keep them on there, but this has nothing to do with ads.
Netflix is a paid subscription service that does not show you ads, yet they have just as strong of an incentive to keep you on their platform as much as possible so you don't go to a competitor. This is simply the nature of online services -- a better online service keeps you on there longer, and in a world of significant online competition, everyone is trying to suck you in.
The same is true of all media really, including books (e.g. the various tactics used by the authors of novels to keep the reader turning the next page). It's just that online media is more potent and compelling to most people so the effect is more noticeable.
