Ars Technica - “Not a good look”: Google’s ad tech monopoly defense widely criticized

According to senior policy analyst Karina Montoya, the "spaghetti football" chart, intended to illustrate industry fluidity, instead caused confusion and potentially undermined Google's argument in the ad tech monopoly trial.

Google wound down its defense in the US Department of Justice's ad tech monopoly trial this week, following a week of testimony from witnesses that experts said seemed to lack credibility.

The tech giant started its defense by showing a widely mocked chart that Google executive Scott Sheffer called a "spaghetti football," supposedly showing a fluid industry thriving thanks to Google's ad tech platform but mostly just "confusing" everyone and possibly even helping to debunk its case, Open Markets Institute policy analyst Karina Montoya reported.

The effect of this image might have backfired as it also made it evident that Google is ubiquitous in digital advertising," Montoya reported. "During DOJ’s cross-examination, the spaghetti football was untangled to show only the ad tech products used specifically by publishers and advertisers on the open web."

One witness, Marco Hardie, Google's current head of industry, was even removed from the stand, his testimony deemed irrelevant by US District Judge Leonie Brinkema, Big Tech On Trial reported. Another, Google executive Scott Sheffer, gave testimony Brinkema considered “tainted,” Montoya reported. But perhaps the most heated exchange about a witness' credibility came during the DOJ's cross-examination of Mark Israel, the key expert that Google is relying on to challenge the DOJ's market definition.

Google's case depends largely on Brinkema agreeing that the DOJ's market definition is too narrow, with an allegedly outdated focus on display ads on the open web, as opposed to a broader market including display ads appearing in apps or on social media. But experts monitoring the trial suggested that Brinkema may end up questioning Israel's credibility after DOJ lawyer Aaron Teitelbaum's aggressive cross-examination.
