They do mention one negative societal effect in passing:
> “The result is less news where it is needed most,” Gannett’s lawsuit said. “Communities throughout the United States now do not have a suitable local paper to advise on local events."
Their issue is that there are not enough newspapers(!), which as we all know are the primary source of modern information... Not that the advertising business has corrupted every form of media it touches, to the point where news outlets don't even report events that don't get them views. Advertising has been instrumental in killing journalism as we knew it, and we're all letting it continue to wreak havoc to our other institutions, because, hey... profit.
> Google has accused the DOJ of having a "narrow view of the ad tech market" that's outdated and "doesn’t reflect reality."
Hilarious take, considering adtech has consistently kept the ways it conducts its business hidden from public view. When users of their services are kept in the dark when their data is being collected and how value is extracted from it, is it really surprising that governments have a wildly inaccurate sense of what's going on? "Senator, we run ads."
