I believe purely context-based ads perform just as well while avoiding hundreds of the downstream negative consequences for society.
The fine-grained user tracking is mostly there so that the big platforms can *market* themselves as having some ad targeting superpower which there's actually scant evidence for.
These over-complex ad systems are actually worse for the advertiser because their complexity makes them opaque and unpredictable.
@nottrobin @bagder So you think everybody who advertises on facebook and such are fooled by some scam by Big Ad? And that Cambridge Analytica had worthless data and that all the political parties are wrong thinking they gain an advantage microtargetting users for their political ad?
Imo the idea that "tracking users for ads works, actually" is much much more plausible.
