Google Holds Illegal Monopolies in Ad Tech, US Judge Finds, Allowing US to Seek Breakup

Alphabet's Google illegally dominated two markets for online advertising technology, a judge ruled on Thursday, dealing another blow to the tech giant and paving the way for US antitrust prosecutors to seek a breakup of its advertising products.

US District Judge Leonie Brinkema in Alexandria, Virginia, found Google liable for "willfully acquiring and maintaining monopoly power" in markets for publisher ad servers and the market for ad exchanges which sit between buyers and sellers. Publisher ad servers are platforms used by websites to store and manage their ad inventory.

Antitrust enforcers failed to prove a separate claim that the company had a monopoly in advertiser ad networks, she wrote.

Lee-Anne Mulholland, vice president of Regulatory Affairs, said Google will appeal the ruling.

"We won half of this case and we will appeal the other half," she said, adding that the company disagrees with the decision on its publisher tools. "Publishers have many options and they choose Google because our ad tech tools are simple, affordable and effective."

Google's shares were down around 2.1% at midday.

The decision clears the way for another hearing to determine what Google must do to restore competition in those markets, such as sell off parts of its business at another trial that has yet to be scheduled.

The DOJ has said that Google should have to sell off at least its Google Ad Manager, which includes the company's publisher ad server and ad exchange.

Google now faces the possibility of two US courts ordering it to sell assets or change its business practices. A judge in Washington will hold a trial next week on the DOJ's request to make Google sell its Chrome browser and take other measures to end its dominance in online search.

Google has previously explored selling off its ad exchange to appease European antitrust regulators, Reuters reported in September.

Brinkema oversaw a three-week trial last year on claims brought by the DOJ and a coalition of states.

Google used classic monopoly-building tactics of eliminating competitors through acquisitions, locking customers in to using its products, and controlling how transactions occurred in the online ad market, prosecutors said at trial.

Google argued the case focused on the past, when the company was still working on making its tools able to connect to competitors' products. Prosecutors also ignored competition from technology companies including Amazon.com and Comcast as digital ad spending shifted to apps and streaming video, Google's lawyer said.

The State Department is warning US diplomats of attempts to impersonate Secretary of State Marco Rubio and possibly other officials using technology driven by artificial intelligence, according to two senior officials and a cable sent last week to all embassies and consulates.

The warning came after the department discovered that an impostor posing as Rubio had attempted to reach out to at least three foreign ministers, a US senator and a governor, according to the July 3 cable, which was first reported by The Washington Post.

The recipients of the scam messages, which were sent by text, Signal and voice mail, were not identified in the cable, a copy of which was shared with The Associated Press.

“The State Department is aware of this incident and is currently investigating the matter,” it said. “The department takes seriously its responsibility to safeguard its information and continuously takes steps to improve the department’s cybersecurity posture to prevent future incidents.”

It declined to comment further due to “security reasons” and the ongoing investigation.

One of the officials said the hoaxes had been unsuccessful and “not very sophisticated.” Nonetheless, the second official said the department deemed it “prudent” to advise all employees and foreign governments, particularly as efforts by foreign actors to compromise information security increase.

The officials were not authorized to discuss the matter publicly and spoke on condition of anonymity.

“There is no direct cyber threat to the department from this campaign, but information shared with a third party could be exposed if targeted individuals are compromised,” the cable said.

The FBI warned in a public service announcement this past spring of a “malicious text and voice messaging campaign” in which unidentified “malicious actors” have been impersonating senior US government officials.

The scheme, according to the FBI, has relied on text messages and AI-generated voice messages that purport to come from a senior US official and that aim to dupe other government officials as well as the victim’s associates and contacts.

It is the second high-level Trump administration official to face such AI-driven impersonation.

The government was investigating after elected officials, business executives and other prominent figures received messages from someone impersonating President Donald Trump’s chief of staff, Susie Wiles. Text messages and phone calls went out from someone who seemed to have gained access to the contacts in Wiles’ personal cellphone, The Wall Street Journal reported in May.

Some of those who received calls heard a voice that sounded like Wiles, which may have been generated by artificial intelligence, according to the newspaper. The messages and calls were not coming from Wiles’ number, the report said.
