The investigation concerns Google’s proposals to remove third-party cookies (TPCs) on Chrome and replace TPCs functionality with a range of ‘Privacy Sandbox’ tools, while transferring key functionality to Chrome.

The CMA is particularly interested to hear any views on whether the proposed commitments are sufficient to address the CMA’s competition concerns regarding:

- unequal access to the functionality associated with user tracking

- self-preferencing Google’s own ad tech providers and owned and operated ad inventory

- imposition of unfair terms on Chrome’s web users

Spin off your surveillance tech, and there will be no problem. Oh wait...
