W3C's Attribution Level 1 proposal criticized as advertising cartel in browser (blog.zgp.org)

• W3C's Attribution Level 1 embeds ad tracking in browsers without user consent
• System favors Big Tech platforms over independent publishers
• Proposal lacks privacy protections and incentivizes riskier data collection

"A blog post by Don Marti criticizes the W3C's proposed 'Attribution Level 1' standard, which would embed advertising measurement into browsers. The author argues that this system, supported by Meta, Google, Apple, and Mozilla, lacks consent mechanisms and would disadvantage smaller publishers while incentivizing riskier data collection. The post warns that the narrow mathematical privacy goals do not address real-world harms and that the standard would strengthen Big Tech's control over advertising."
