substitution effects
Previously: Arguments for the attribution cartel
One of the arguments for the attribution cartel is that in-browser attribution tracking will somehow displace other forms of ad measurement. Because reasons, I guess. Or because the cartel members believe that they can convince people that everyone else’s ad data collection needs consent—or at least those fake “consent” dialogs that the Irish regulators will let you get away with—and somehow the attribution cartel doesn’t.
The problem with that argument is that there have already been two big opportunities for substitution effects to happen. And they haven’t.
Google’s “Privacy Sandbox” included an Attribution Reporting API. But as far as I can tell it was the only one of the major “Privacy Sandbox” ad systems not to get an independent test. (If I’m wrong, let me know and I’ll add it to the timeline.)
Apple Safari has “privacy-preserving ad attribution” that came out in 2021, but as far as I can tell most of the people talking about it are users who found it buried under “Advanced” in settings and are talking about turning it off.
Why so little marketer interest in an in-browser ad measurement system?
The problem is that for the attribution cartel, the system has a limited set of acceptable outputs. The Google and Apple systems would have had to agree that the best-performing ads are on Google and Apple properties.
Likewise, whatever W3C ends up standardizing on, the attribution reports will have to agree with the ad placement decisions already made by the Facebook and Instagram algorithms, by Google’s Performance Max, and by whatever Apple is going to be doing as they continue to enshittify over there. Imagine an attribution report that contradicted the optimal placements decreed from above, and gave credit for sales to legit independent sites instead. That would be like writing a biology paper contradicting Trofim Lysenko back when he was a big shot.
Since marketers can predict that the attribution reports are going to hide the halo effects of the likely most impactful ad placements, and just back up what the cartel members were saying anyway, there was little interest in the Google and Apple systems, and there will be little interest in the new one. The attribution cartel members have reasons to do what they’re doing—but they have to do with lobbying and consolidation, not benefits to legit advertisers or legit ad-supported sites.

collect location data, they’re putting users at risk of more than just
creepy ads. Location information sourced from the advertising industry

Reuters Built Its Own AI Model That Now Ranks Among the World’s Best -
Thomson Reuters Institute by Joel Hron and Jonathan Schwarz.
Thomson is competitive with the world’s leading frontier models
despite being a fraction of their size and cost to train and operate.
Thomson Reuters has achieved that performance by combining exceptional
AI talent with authoritative proprietary content and deep domain
expertise. And with less than 10% of Thomson Reuters content used in its
training so far, there remains significant opportunity to expand its
capabilities.

superstition, ambition, and ignorance on the other.
