Not wrong, it's actually the only part of the article that's correct. The entire adtech industry has seen a race to the bottom due to 3rd-party cookies and audience-based buying of highly-targeted impressions. Things like retargeting and data leakage are endemic problems and basically the entire reason trade groups like DNC exist. These "high paying" advertisers don't exist. Campaigns aren't sold or activated like that. There are brand safety and inventory quality issues but "prestige and association" is not as important as you might think, and all media agencies have been focused on backing into the lowest CPM for the last decade. It's finally being (forcefully) solved through cookie blocking and privacy regulation leading to the rise of first-party data again, however that makes walled gardens like Facebook and Google stronger too at the same time which brings a whole new set of problems.
