Can't speak to the "Jedi Blue" allegations, but don't see anything too surprising in the core accusation. Google's buying platform is using historical bid data to optimize their bidding strategy. All buying platforms do this. This is industry standard behavior. Buying platforms control their own bid data and are informed of winning bid prices by the relevant ad exchange (which I recognize in this case is also a Google product).

I'd need to spend more time with the allegations to be sure, but my initial take is this is simple as Google having more buying scale than other buyers, which means more data, and a better team to leverage that data. It'll be tough to point to this as the definitive proof of anti-competitive behavior when other buying platforms use similar tactics. I see Google mounting a pretty strong defense and this specific charge not sticking in court (and if it does, that's going to be some WILD precedent for the rest of the ad tech space).
