AI’s shared opt-out still leaves publishers with separate bargains
Research and verification notes
10 November 2026. Author: Ivan Massow.

The article compares original provider announcements and current documentation with the individual IETF proposal and published reporting from Digiday. Plans are identified as plans. Google Search controls, Gemini training and grounding are different scopes. No publisher’s adoption of the shared signal is asserted. The restaurant-review example is hypothetical.

Noah, a research and forecasting service, supplied an analysis of publishing coverage and a follow-up check. Source-result counts and overlapping coverage were not treated as adoption, independent corroboration, public opinion or probabilities. Original sources govern the technical claims. No downstream compliance, referral uplift or licence revenue is inferred from announcements.

No publishable final probabilities were returned. The automatic quick-forecast stage ended with the non-retryable error: "forecast source exclusion exceeds the 160-character limit". The service had interpreted part of the research brief as a source exclusion. No replacement forecasts were commissioned and no preliminary or host estimates are published. This limitation does not affect the independently checked reporting.

Josh Muncke, Vice-president of generative AI, The Economist Group: "I don’t believe we’ve tested it yet". Short excerpt reported by Jessica Davies and Seb Joseph in Digiday on 9 November 2026 from its Media Strategies event. Context: the separate CMA-related Google Search controls, not adoption of the shared training signal. Neither quotation is from a Tomorrow’s Publisher interview.
