Google's browser cookies plan anti-competitive, advertisers tell EU

BRUSSELS, Sept 28 (Reuters) - Google's (GOOGL.O) plan to block a popular web tracking tool called "cookies" is anti-competitive, a group of advertisers, publishers and tech companies said in a complaint to EU antitrust regulators.

The grievance could boost the European Commission's investigation opened in June into Alphabet unit Google's Privacy Sandbox which the company said could allow businesses to target clusters of consumers without identifying individuals.

Google said a year ago that it would ban some cookies in its Chrome browser to increase user privacy and offer the Privacy Sandbox as an alternative.

The Movement for an Open Web (MOW) said the proposal would give Google the power to decide what data can be shared on the web and with whom.

"Google says they're strengthening 'privacy' for end users but they're not, what they're really proposing is a creepy data mining party," MOW lawyer Tim Cowen said in a statement.

The Commission confirmed receipt of the complaint, saying it would assess it under the standard procedures. In June, it kicked off an investigation into Google's online display advertising technology services.

Google has offered to settle the case in a bid to avoid a possible fine and a disruptive prolonged probe, a person familiar with the matter told Reuters last week. read more

Google declined to comment on the MOW complaint and referred to its previous statement released when it offered concessions to the UK competition watchdog, which described the Privacy Sandbox as an open initiative to provide strong privacy for users while also supporting publishers.

The U.S. Justice Department is also examining the issue, people familiar with the matter have told Reuters. read more

The group's complaint to the UK regulator prompted its investigation which subsequently led Google to offer concessions.
