A WIRED study of the 10,000 most popular websites finds many disclose sharing user data with hundreds to over 1,800 advertising partners via cookie consent pop-ups, revealing the scale and opacity of the ad-tech ecosystem; data may include IP addresses, device fingerprints, and identifiers, with disclosures shaped by IAB Europe standards and consent management platforms.
