DOJ claims Google has "trifecta of monopolies" on Day 1 of ad tech trial

Google’s Role in the Web Ecosystem

• Many argue Chrome and Google’s dominance in web standards lets them protect ad and platform monopolies, weaken privacy, and avoid commoditization of Android APIs.
• Others counter that Google “saved” the web, pushed PWAs, and enabled sophisticated web apps (e.g., Figma‑like) versus a world dominated by locked-down app stores.
• There’s nostalgia for a Firefox‑led ecosystem, but recognition that Mozilla is financially dependent on Google.

Third‑Party Cookies and Conflicts of Interest

• Several comments say third‑party cookies likely persisted mainly because Google feared antitrust fallout from killing them.
• Mixed views: technically useful for some benign cases, but widely abused and mostly unwanted by privacy‑minded users.
• Consensus that having the dominant browser vendor also be a top ad‑tech player creates deep conflicts of interest.

Ad‑Tech “Trifecta” and Market Structure

• Core allegation discussed: Google dominates three layers of display ads—publisher ad server, ad exchange, and advertiser tools (“sell side,” “auction,” “buy side”).
• Commenters describe Google as simultaneously exchange, broker, market‑maker, and a big advertiser, with insider data and control over auction rules.
• Examples raised include Jedi Blue (coordination with Facebook) and Project Bernanke (tweaking auctions to benefit Google’s side), though details and interpretations are disputed.
• Some ad‑tech practitioners stress the product maze is confusing even for insiders and may be intentionally so.

Effects on Publishers, Newspapers, and Advertisers

• DOJ narrative (as relayed in comments): Google’s position lets it both underpay publishers and overcharge advertisers, skimming large margins.
• Some say this likely worsens the economics for news sites already hit by the loss of classifieds and changing reader behavior.
• Others are skeptical that Google alone “killed newspapers,” pointing instead to Craigslist, the open Internet, and weak demand for paid journalism.

Antitrust Standards, Outcomes, and Comparisons

• Discussion contrasts U.S. “consumer welfare” (price‑focused) with broader European dominance standards; some see both as ill-suited to “free” ad‑funded services.
• Debate over whether breaking up monopolies is usually good: many cite Standard Oil, AT&T, airlines; others note mixed or negative cases (rail, energy, post‑Soviet transitions).
• Some think this is the strongest antitrust case against Google (clear market structure, measurable economic harm); others doubt courts will meaningfully act, citing the Microsoft case.

Apple, Meta, Amazon, and Market Power

• Repeated comparisons:
  • Apple—seen by some as a worse mobile gatekeeper (App Store control, 30% cut), but with separate ongoing DOJ actions.
  • Meta—huge in social ads, but perceived as less monopolistic today in social media overall.
  • Amazon—viewed as offering great consumer value while still potentially abusing platform power (especially via AWS and marketplace).
• Some worry that weakening Google on Android could unintentionally strengthen Apple’s mobile dominance in the U.S.

Privacy, Surveillance, and Broader Harms of Ads

• Several express frustration that the case targets competition and publisher harm, not privacy abuses or societal damage from surveillance advertising and attention‑driven media.
• Others reply that antitrust law is about economic harm, and privacy needs separate legislative frameworks.
• There’s a minority view that advertisers mostly want cohorts and distributions, not granular personal data, while others insist advertisers do aggressively seek detailed profiles.

Complexity, Obfuscation, and Public Understanding

• Commenters note that Google’s internal guidance discourages defining “markets” or “market share,” which is seen as defensive lawyering.
• Many argue the technical and contractual complexity of ad‑tech itself serves to hide anticompetitive behavior and make effective regulation harder.
• Overall sentiment: the ad‑tech stack is opaque, misaligned with user interests, and any remedy will be technically and politically messy.
