Halfway through the first day of closing arguments in the Department of Justice’s big antitrust trial against Google, US District Judge Amit Mehta posed the question that likely many Google users have pondered over years of DOJ claims that Google’s market dominance has harmed users.

“What should Google have done to remain outside the crosshairs of the DOJ?” Mehta asked plaintiffs halfway through the first of two full days of closing arguments.

According to the DOJ and state attorneys general suing, Google has diminished search quality everywhere online, primarily by locking rivals out of default positions on devices and in browsers. By paying billions for default placements that the government has argued allowed Google to hoard traffic and profits, Google allegedly made it nearly impossible for rivals to secure enough traffic to compete, ultimately decreasing competition and innovation in search by limiting the number of viable search engines in the market.
