The core issue here is that this regulation doesn't directly introduce any new competition while it only tries to weaken Google's network effect. Network effect is a new corporate tool to fight against antitrust regulation; it's not that straightforward to handle it within the scope defined by the US antitrust jurisprudence especially when it actually benefits the consumers (in this case, advertisers). I personally believe that we need to deal with those aggregators but not sure if this kind of breaking up will result anything other than lost opportunity costs from several years wasted from a lawsuit. I hope DoJ to develop a new effective framework to regulate aggregators but it's very unlikely since William Barr seems to be mostly driven by political motivation.
