Apple outlines a broader plan to block web-tracking infrastructure
Apple has published its clearest plan yet to limit third-party web tracking, arguing that cookie blocking alone no longer addresses identity resolution, fingerprinting and related techniques. The WebKit team says users should not be tracked across websites or covertly unless they explicitly opt in, raising the stakes for ad tech, mar tech and vendors built around identity graphs.
Why it matters: Marketers should understand how Apple’s proposed privacy changes could weaken cross-site and cross-device targeting and measurement, then reassess reliance on identity resolution, first-party data, consented relationships and alternative measurement approaches. The evidence is strong for what Apple announced, but the cluster provides limited independent reporting on implementation details and timing.
