Google’s Privacy Sandbox Faces UK Competition Complaint
Digital Marketing Coalition Challenges Google’s Cookie Phase-Out
A coalition of digital marketing firms has filed a formal complaint with the UK’s Competition and Markets Authority (CMA) against Google’s Privacy Sandbox initiative, which aims to phase out third-party tracking cookies. The group, calling itself Marketers for an Open Web (MOW), is requesting regulators delay the planned 2021 implementation to allow time for competitive safeguards.
Key Concerns Raised by MOW:
- Claims Privacy Sandbox would cement Google’s dominance in digital advertising
- Argues the initiative threatens the open web ecosystem
- Requests CMA impose interim measures to suspend implementation
Regulatory Response and Background
The CMA confirmed receiving the complaint, noting some concerns align with findings from their 2020 online ad market study. While no investigation decision has been made, the regulator stated:
“We take the matters raised in the complaint very seriously… If urgency requires, we may impose interim measures.”
Google’s Defense:
A company spokesperson emphasized Privacy Sandbox is an open initiative designed to:
- Enhance user privacy
