UK data watchdog questions how private Google's Privacy Sandbox is

A draft report from the UK ICO reportedly finds Google’s Privacy Sandbox insufficiently private, raising concerns that it still enables cross-site tracking, while the UK CMA warns it could disadvantage competitors. The IAB argues current designs may hinder effective advertising and hurt smaller players, and Google counters that the Sandbox delivers meaningful privacy improvements and remains engaged with regulators. These pressures could delay Chrome’s deprecation of third-party cookies as Google works to address privacy and competition issues.
