What Google Gave Back, and When

In December 2025, Google Ad Manager publishers got a change that yield teams had been asking for since 2019: the ability to set different price floors for different bidders again. Unified pricing rules, which had forced one floor across all indirect programmatic demand, were removed (Search Engine Land, 2025). Trade coverage did not describe it as a feature launch. It described it as a response to antitrust pressure in the United States and Europe (Press Gazette, 2025).

That is the pattern this chapter maps. Every significant publisher-favorable change to Google’s sell-side stack over the last seven years arrived within a measurable distance of an enforcement event. Not one of them arrived because a publisher asked. The useful exercise is to line the concessions up against the docket and see what the sequence implies about how the roadmap was actually set.

2019: Giving Up Last Look, Taking Away Floors

Google announced in March 2019 that Ad Manager would move to a first-price unified auction, with the rollout running through the rest of that year (Google Ad Manager Blog, 2019), and confirmed the completed transition later in 2019 (Google Ad Manager Blog, 2019). This is where last look ended. The mechanic and its consequences are the subject of The Last Look.

Taken alone, it is a real concession. AdX gave up a genuine informational advantage. Taken as shipped, it is more complicated, because the same package introduced unified pricing rules: one floor across all indirect demand, capped at 100 rules. Publishers lost the ability to price differently against different exchanges, which was the only lever they had for pushing back on AdX’s fee without leaving Ad Manager entirely.

The timing is worth noting. March 2019 sits after the Texas-led state investigation had begun organizing and well into the period when European and American regulators were actively examining Google’s ad tech. Header bidding adoption was also at its peak, meaning last look was already leaking value. Giving up an advantage the market had partly neutralized, while acquiring a new restriction on publisher pricing, is not the shape of a company retreating under pressure. It is the shape of a company trading.

Jedi Blue: Alleged in 2020, Dismissed in 2022

The most quoted controversy in this history is also the one least supported by a court.

In the Texas-led multistate complaint, state attorneys general alleged that a September 2018 agreement between Google and Facebook, code-named Jedi Blue inside Google, induced Facebook to abandon its header bidding efforts in exchange for preferential terms in Google’s Open Bidding programme. The allegations included bid rate and win rate commitments, information advantages, and a minimum annual spend, with sign-off reaching the chief executives of both companies. The European Commission and the UK’s Competition and Markets Authority opened parallel formal investigations into the agreement in March 2022 (TechCrunch, 2022).

In September 2022, Judge P. Kevin Castel dismissed the Jedi Blue claim. He found valid business justifications for the agreement, writing that there was nothing inexplicable or suspicious about the two companies entering it, and pointing to Facebook’s ordinary interest in driving the hardest bargain it could and Google’s ordinary interest in winning as much of Facebook’s business as possible (Adweek, 2022). The rest of the states’ case survived. Jedi Blue did not (Engadget, 2022).

Anyone writing about this history should stop calling Jedi Blue a proven conspiracy. It was an allegation, it was tested, and it lost on the merits at the pleading stage. The European Commission’s eventual 2025 adtech decision rested on self-preferencing in Google’s own auction, not on the Meta agreement.

Project Bernanke: The Opacity Evidence That Held Up Better

The stronger evidence of auction opacity is a set of internal programs that got far less press.

The states’ third amended complaint, unredacted in January 2022, alleged that Google ran what amounted to a third-price auction inside AdX while publicly describing the auction as second-price. Under the program the states called Bernanke, AdX would in some cases pass the publisher a lower clearing price than the second bid implied, charge the advertiser closer to the second-price amount, and pool the difference into a fund used to top up bids from advertisers buying through Google’s own tools (Techdirt, 2022). A later variant the complaint called Global Bernanke pooled that value across publishers rather than within a single one (Ad Tech Explained).

The number that made this land was Google’s own. According to the state attorneys general, internal Google analysis found the practice could reduce some publishers’ revenue by as much as 40% (Engadget, 2021). Bernanke was one of a family of programs named in the litigation alongside Reserve Price Optimization and Dynamic Revenue Share, all of which involved Google adjusting auction parameters using information publishers and advertisers could not see.

Precision matters here. These remain allegations in the states’ case, and Google has disputed the characterization, describing the programs as bid optimization rather than deception. What distinguishes them from Jedi Blue is that the underlying conduct, not just the theory, carried into the federal case. The DOJ’s account of price manipulation through auction parameter changes was argued at trial before Judge Brinkema (Tech Policy Press). Jedi Blue was dismissed. The opacity conduct was litigated to judgment.

2025: Liability in Virginia, a Fine in Brussels

On April 17, 2025, Judge Leonie Brinkema found Google liable for monopolizing the open-web publisher ad server market and the open-web display ad exchange market, and for unlawfully tying DFP to AdX (CNBC, 2025). The opinion did not find liability across every claim. The DOJ failed to establish a relevant market for open-web display advertiser ad networks, which is the buy-side half of the stack covered in The Acquisition That Bought a Filing Cabinet. Two markets out of three, plus the tie.

On September 5, 2025, the European Commission fined Google €2.95bn for abusing its dominant position in publisher ad servers and programmatic buying tools by favouring AdX in ad selection and in how Google Ads and DV360 bid into exchanges, conduct the Commission traced back to at least 2014. Google was ordered to end the self-preferencing and given 60 days to submit a compliance plan, with the Commission stating a preliminary view that only a structural remedy, meaning divestiture, may be sufficient (European Commission, 2025). The fine was reported at roughly $3.45bn (CNBC, 2025).

Both proceedings converged on the same structural fact from different legal traditions, and both left the remedy open. The comparative theories, and why divestiture is easier to order than to execute, are worked through in Remedies.

December 2025: The Floors Come Back

Then came the release note. Unified pricing rules, introduced in 2019 as part of the first-price package, were removed from Ad Manager in December 2025. Publishers can once again set bidder-specific floors, and yield teams began estimating mid-single-digit to low-double-digit revenue upside from differential pricing (Search Engine Land, 2025).

The court had already characterized unified pricing rules as limiting publishers’ ability to set floor prices, which put the feature squarely inside the conduct at issue in both the US and EU proceedings (Press Gazette, 2025). Google did not remove it in 2020, when publishers complained loudly. It did not remove it in 2022, when the EU and UK opened investigations. It removed it in December 2025, after a liability finding in Virginia and a €2.95bn fine in Brussels.

What Was Not Given Back

The concession list is short, and reading it next to the list of things that did not change is the fastest way to see what enforcement has and has not reached.

The AdX open auction fee stayed at roughly 20% throughout, including through a period when Google’s own internal analysis put the price above the value delivered, as covered in The 20% That Never Moved. The tie itself stayed. DFP and AdX remain one product with one contract, which is the arrangement Brinkema found unlawful in April 2025 and which no announced change has altered. Publishers still cannot audit the final allocation decision on an impression. Open Bidding still runs inside infrastructure operated by the largest bidder in it.

The auction parameter programs named alongside Bernanke are instructive on this point. Reserve Price Optimization used publisher-specific historical bid data to set floors, and Dynamic Revenue Share adjusted Google’s own cut on individual impressions rather than applying a fixed percentage. Both were discontinued or restructured, and neither ended in a way that gave publishers a new capability. They ended by being removed from a system publishers still could not see into (Techdirt, 2022). Removing an undisclosed practice is not the same concession as granting visibility, and the difference is exactly why the DOJ’s remedy proposals moved past conduct rules toward structural separation and disclosure of the auction logic.

So the honest ledger reads: one informational advantage surrendered in 2019, in a package that took a pricing lever away. One restriction reversed in December 2025, after a liability finding and a €2.95bn fine. Several undisclosed programs withdrawn without replacement. The fee, the bundle, and the opacity intact.

Compliance Engineering Is a Roadmap

Read the sequence as a product manager rather than as a lawyer and the pattern is uncomfortable.

Concession	Date	Nearest enforcement event	Publisher benefit	What Google kept or gained
Last look removed inside Open Bidding	2017	header bidding at peak adoption, early regulatory interest	rival exchanges bid on equal terms server-side	the auction moved back inside Google’s infrastructure
First-price unified auction	2019	state investigations organizing, EU adtech scrutiny building	one auction, no privileged look for AdX	unified pricing rules removed bidder-specific floors
Jedi Blue terms defended, not changed	2022	Castel dismissal, EU and UK probes opened	none	the agreement survived on valid business justification
AdX fee held at roughly 20%	throughout	internal 15% proposal declined	none	full monopoly rent, as covered in the previous chapter
Unified pricing rules removed	December 2025	April 2025 liability finding, September 2025 EU fine	bidder-specific floors restored	nothing obvious, which is the point

The last row is the one that changes the reading of all the others. In 2017 and 2019, Google conceded things it was going to lose anyway, and attached a new restriction on the way out. In December 2025, it conceded something with no offsetting gain, because a federal court had already found the conduct unlawful and a European regulator had already priced it. That is not a negotiation. That is a compliance deliverable.

For anyone building on Google’s sell-side stack, the operational lesson is that the roadmap has an input the release notes never mention. Features arrive and disappear on a schedule set partly in Alexandria, Virginia and partly in Brussels. The single-floor constraint that yield teams designed around for six years was not a product decision that could be argued with on product grounds, and it did not go away for product reasons either. Whether the remaining structure survives the remedies phase, and what a divested exchange would even look like, is where this book turns in Remedies. Before that, the honest summary of the record is short. Google gave publishers back the things it was ordered to, roughly when it was ordered to, and not before.
