Big Tech and Antitrust: What Each Position Is Protecting

On August 5, 2024, a federal judge in Washington, D.C. ruled that Google had illegally maintained a monopoly in internet search — the first time an American court had found a major technology company a monopolist since the Microsoft case of 2000. The following spring, a second federal judge found Google had also monopolized the online advertising technology market, determining that Google's 20% fee on publisher ad sales had been maintained for a decade through deliberate anticompetitive conduct. In November 2025, a different federal judge dismissed the FTC's case against Meta — ruling that the government had failed to prove Meta currently held a monopoly in personal social networking, because TikTok and YouTube had transformed the competitive landscape since the complaint was filed five years earlier. Meanwhile, the European Union fined Apple €500 million under its Digital Markets Act for steering users away from rival app stores, and Amazon settled a separate case about manipulative "dark patterns" on Prime subscriptions for $2.5 billion.

These events are simultaneous and contradictory. They suggest both that antitrust enforcement is having a real impact and that it is losing some of its most ambitious cases. The debate around Big Tech and antitrust is not really about whether these companies are powerful — their market caps, their data holdings, and their role in daily life make that obvious. It is about what that power means, who it harms, what kind of legal tools can address it, and whether the solution is to break these companies apart, constrain how they operate, require them to open their systems to rivals, or change who owns them in the first place. Each of these answers is protecting something real.

What the structural-breakup position is protecting

The argument that concentrated private economic power is inherently dangerous to democratic self-governance, worker bargaining power, and the possibility of entrepreneurial competition — and that the only way to restore those things is to dismember the companies that have accumulated it. This position, often called neo-Brandeisian after Supreme Court Justice Louis Brandeis, is associated with scholars and advocates including Lina Khan (former FTC Chair and author of the 2017 Yale Law Review article "Amazon's Antitrust Paradox"), Matt Stoller (author of Goliath: The 100-Year War Between Monopoly Power and Democracy), and Zephyr Teachout (author of Break 'Em Up). Its animating claim is that the United States made a catastrophic conceptual error in the 1970s: narrowing the purpose of antitrust law to "consumer welfare," typically measured by whether prices to end consumers are low, when the Sherman Act's original purpose was much broader.

The consumer welfare standard, formalized by Robert Bork's 1978 book The Antitrust Paradox, made antitrust nearly toothless against platform companies whose services are nominally "free." If your definition of harm is higher prices, you cannot easily sue a company that gives away search, email, and maps at no charge. Khan's core intellectual contribution was to show that this misses how platform power actually works. Amazon could price below cost indefinitely because it was building data, logistics, and marketplace infrastructure that would compound over time into a position from which recoupment doesn't come through price increases — it comes through structural control. When you own both the marketplace and sell goods on it, when you run the ad exchange and also place ads on it, when you control the app store and also compete in app categories, you have a built-in structural advantage that no individual competitor can overcome regardless of how good their product is.

The deeper argument is political. Stoller's work emphasizes that monopolists become political actors who lobby to preserve their own dominance, capture regulatory agencies, and make competitive markets functionally impossible to restore through normal democratic processes. Google paid Apple alone an estimated $18–20 billion per year to remain the default search engine on Safari — a payment that simultaneously entrenched Google's search monopoly and made Apple financially dependent on Google's continued dominance. The argument that Facebook's acquisitions of Instagram in 2012 and WhatsApp in 2014 were "buy or bury" strategies — acquire potential rivals before they threaten the core business — is not a market efficiency argument or a consumer price argument. It is an argument about the structural conditions for competition itself. What this position is protecting: the proposition that open, competitive markets require active maintenance, that private economic power and democratic political power are in permanent tension, and that allowing a small number of companies to become intermediaries for the entire digital economy is not a neutral outcome.

The structural-breakup position also carries a "kill zone" argument: that venture capital firms have become reluctant to fund startups in areas adjacent to Google, Meta, Apple, Amazon, and Microsoft, because the realistic exit scenarios are either acquisition by the incumbent or destruction by it. The innovation case for antitrust is not that these companies are bad at innovating — they are extraordinarily capable — but that by foreclosing independent competition, they may be suppressing innovations that wouldn't survive inside a large corporation's strategic priorities.

What the consumer welfare standard is protecting

The argument that economic efficiency and consumer benefit are the correct and bounded purposes of antitrust law — and that expanding antitrust to pursue political, distributional, or populist goals introduces so much discretion that the law becomes a weapon politicians can deploy against any large company they dislike. This position, associated with scholars including Geoffrey Manne (founder of the International Center for Law and Economics), Joshua Wright (George Mason University, former FTC Commissioner), and, in its foundational texts, Robert Bork, argues that the neo-Brandeisian movement is "hipster antitrust" — dressed-up economic nationalism or political grudge-settling that would harm the same consumers it claims to protect.

The Chicago School's most powerful argument is that large firms with high market shares are not automatically harmful. A firm can achieve a 90% market share by building a genuinely superior product — and punishing it for that success is economically incoherent. Judge Mehta's Google search ruling acknowledged exactly this: Google became dominant through a genuinely preferred product. The legal issue was the exclusive default agreements with Apple and Samsung, not the quality of search. The Chicago School would argue this is the consumer welfare standard working as intended — the antitrust problem is narrow and precisely targeted at specific conduct, not a general anxiety about bigness.

The November 2025 ruling in FTC v. Meta was the Chicago School's most significant recent vindication. Judge James Boasberg found the FTC's proposed market definition — "personal social networking" excluding TikTok and YouTube — "unduly narrow" and its theories "logically incoherent, internally contradictory, economically irrational, or clearly contradicted by the record." This is precisely the Chicago School's market-broadening argument: the platforms compete with each other for attention, advertising dollars, and user time, and artificially narrow market definitions that exclude obvious substitutes do not reflect how consumers actually behave.

There is also an innovation argument that goes beyond defensive efficiency claims. The companies under antitrust attack are among the largest investors in AI research, cloud infrastructure, and foundational science in the world. Google DeepMind, Meta's FAIR research lab, and Amazon's AWS infrastructure have produced genuine public goods. The argument is not that these companies deserve immunity because they innovate, but that structural remedies — forced divestiture, mandated data-sharing, prohibited vertical integration — create uncertainty that could make large-scale, long-horizon technical investment less attractive to precisely the kinds of organizations capable of undertaking it. What this position is protecting: the proposition that markets reward competitive success, that predictable legal rules are necessary for economic planning, and that government power to redesign successful businesses is dangerous regardless of who the current target is. Wright's conservative version of this warning has a pointed edge: if the government can order Google to restructure its products to reduce its market share, the same legal authority could be used by a different administration against companies whose content moderation it dislikes.

What the behavioral regulation and interoperability position is protecting

The argument that competitive dynamics can be restored — and platform lock-in dismantled — without destroying the organizational structures and scale efficiencies that give these companies genuine value. This position accepts that large integrated platforms can produce real benefits for users and the economy. Its concern is not size but switching costs: the friction that traps users, advertisers, and developers inside particular ecosystems not because those ecosystems are best, but because leaving is too costly. Tim Wu, who coined "net neutrality" and later served as a Biden White House technology adviser, articulates this most clearly: the solution to Google's monopoly in search is not necessarily to break Google in half but to ban the exclusive default agreements that prevented alternatives from competing for attention and to require Google to share search index data with rivals.

The European Union's Digital Markets Act, which entered into force in March 2024 and began generating enforcement actions in 2025, is the most ambitious attempt to operationalize this vision. Rather than waiting for a decade-long case-by-case adjudication process, the DMA designates "gatekeeper" platforms and imposes ex-ante obligations: mandatory messaging interoperability, data portability requirements, prohibitions on self-preferencing, requirements that app stores permit alternative payment systems. Apple was fined €500 million in April 2025 for continuing to steer users away from third-party app alternatives in violation of DMA rules. Meta was fined €200 million for its "pay or consent" advertising model. The DMA's insight is structural: antitrust litigation moves too slowly. By the time a case is filed, tried, appealed, and remedied, the market has transformed — as FTC v. Meta demonstrated by becoming obsolete mid-trial.

The interoperability argument has a long history in communications infrastructure. Telephone networks were required to interconnect: you could call an AT&T customer from a Sprint phone. The cable modem market was opened by access mandates. Wu's argument, developed in The Master Switch: The Rise and Fall of Information Empires (2010), is that the history of communications industries follows a cycle: open and chaotic in their youth, captured by a dominant firm in their maturity, and eventually requiring structural intervention to restore openness. The digital platforms are following the same arc, and behavioral mandates — not breakups — are the historically proven intervention.

Writer and technologist Cory Doctorow, who coined the term "enshittification" to describe the predictable decline of platform quality as network effects trap users, makes the interoperability argument in its most radical form. He argues for "competitive compatibility" — allowing third parties to build interoperable tools on top of dominant platforms without permission, the way early internet protocols were designed. The result would be that dominant platforms cannot fully extract value from their users because users can always route around extraction via compatible alternatives. What this position is protecting: the proposition that competition is a condition that can be structurally maintained without requiring continuous litigation or structural dissolution — that open standards, data portability, and interoperability mandates are the proper vocabulary for regulating digital infrastructure.

What the platform cooperativism position is protecting

The argument that the ownership structure of platforms — not just their market structure — is the fundamental problem, and that breaking up investor-owned platforms into smaller investor-owned platforms changes the scale but not the logic of extraction. This position, developed by scholars including Trebor Scholz (The New School) and Nathan Schneider (University of Colorado Boulder), begins from an observation that the other three positions largely share: platforms aggregate the contributions of millions of workers, creators, and users into network effects that generate enormous value — and then distribute that value almost entirely to investors and executives rather than to the people whose contributions made it possible.

Scholz coined the term "platform cooperativism" in a 2014 essay published by the Rosa Luxemburg Foundation: the strategic principle of taking the same technology that Uber, Airbnb, or Amazon uses and running it cooperatively, with ownership and governance held by the workers or users who generate the value. He calls this "cloning the heart" — replicate the technological infrastructure while replacing the extractive ownership structure. Examples include Up&Go, a New York City cleaning workers cooperative that uses smartphone dispatching similar to TaskRabbit; Stocksy, a photographer-owned stock image cooperative; and Resonate, a musician-owned streaming platform. Worker-owned platform cooperatives in the care economy have documented pay increases from $10 to $25 per hour after transitioning from gig-economy contractors to cooperative ownership.

Schneider extends this into a "democratic ownership" framework in Everything for Everyone: The Radical Tradition That Is Shaping the Next Economy (2018). His proposal for "exit to community" describes a model in which startups, when they reach scale and begin generating returns, transition ownership to their user and worker community rather than exiting via IPO or acquisition. This would structurally prevent the "buy or bury" dynamics that drove the FTC's case against Meta — not through regulation but through changing the incentive structures embedded in ownership from the outset. If Instagram had been a user-owned cooperative, Facebook could not have acquired it: there would have been no investors to sell to.

This position does not reject antitrust enforcement. Its proponents are generally sympathetic to breaking up or constraining dominant platforms. But they argue that a competitive market of investor-owned platforms still generates surveillance capitalism, precarious gig work, algorithmic manipulation of attention, and the concentration of wealth at the top. The question this position is asking is not "how many social networks should there be?" but "who owns them, and to whose benefit do they operate?" What this position is protecting: the proposition that markets are built from institutions, and institutions can be designed differently — that the cooperative, the mutual, the commons, and the public utility are not failures of market design but alternatives to it, with a 200-year track record that conventional economics habitually ignores.
