Research paper argues that Facebook increased user surveillance as its competitors exited the market, makes the case for antitrust action against the company
In 2017, a 28-year-old law student named Lina Kahn turned the antitrust world on its ear with her Yale Law Review paper …
Context & Ripple Effects
This paper lands in the middle of an arc that began when an earlier academic argument framed Facebook's monopoly power and its privacy abuses as two sides of the same coin — the intellectual foundation laid by Lina Kahn's 2017 Yale Law Review work on rethinking antitrust for platform markets. What this piece adds is mechanism: as rivals exited, Facebook's substitute for competition was more surveillance of the users it no longer had to win over.
The empirical side of that claim later surfaced in Facebook's own leaked documents, which showed leadership acting from a conviction that it was vulnerable to rivals — behavior consistent with a company treating competitor exits as license to extract more from users. That evidence pipeline runs straight into the FTC and state AG complaints of late 2020.
First-order effects
- Antitrust enforcers gain a concrete harm theory: the FTC and state AGs' complaints, built on emails portraying Zuckerberg vowing to crush competition, now have scholarly backing tying monopoly to measurable user-harm through surveillance rather than just price effects.
- Facebook faces a reframed legal exposure where every privacy decision doubles as potential evidence of monopolist conduct, collapsing the wall between its regulatory and antitrust battles.
Second-order effects
- When the FTC suit was ultimately dismissed, courts signaled that existing antitrust law struggles to absorb privacy-as-competition arguments — pushing the burden onto lawmakers to rewrite statutes so the theory this paper advances can actually stick.
- Rival platforms and would-be entrants inherit a clearer playbook: demonstrating competitive exit dynamics becomes the route to challenging incumbent data practices, raising the evidentiary stakes on how incumbents document their own market reasoning.
Third-order effects
- If the pattern holds — scholarship supplying harm theories, leaks supplying evidence, litigation testing them — antitrust doctrine shifts from consumer-price welfare toward quality-and-privacy degradation as the standard measure of monopoly harm, with platform gatekeeping as the primary battleground.
- Sustained failure of current law to reach these cases points toward structural separation remedies and new legislation aimed at data-driven incumbents, making the durability of the Facebook-era precedents a live question for whatever dominant platforms come next.
The trend: Antitrust thinking is migrating from price-based harm toward privacy and service-quality degradation as the core evidence of platform monopoly power, with Facebook as the test case.
