Takeaways
Privacy-focused users are often the most valuable customers, challenging traditional ad tech assumptions about measurability.
Attribution is fundamentally about linking ad exposure to outcomes, but current models often prioritize simplicity over accuracy.
“Privacy-preserving” systems frequently focus on mathematical guarantees that don’t align with real-world privacy harms like discrimination or deception.
Proposed attribution standards may unintentionally increase surveillance incentives by enabling fraud and data laundering.
Fraud in attribution systems can reward actors who intercept users right before purchase, distorting true performance signals.
Big tech companies may benefit from attribution systems that reinforce their own ad recommendations, reducing competition.
The “halo effect” shows ads perform better in trusted, premium environments, but current systems undervalue this dynamic.
A shift toward cheap, commoditized ad placements weakens both brand equity and publisher sustainability.
The so-called “attribution cartel” is defined by systems that avoid user consent and bypass opt-out mechanisms.
Effective privacy regulation should focus on real-world harms rather than technical implementation details.
