Sources: EU antitrust investigators have deepened their inquiry and sought internal Facebook documents related to alleged efforts to squash potential rivals
Authorities have sought documents related to allegations that company leveraged access to user data to stifle competition
Context & Ripple Effects
This report is the early evidence-gathering phase of what became a multi-year, multi-jurisdiction case. It follows complaints from rivals on both sides of the Atlantic — including the Snap-compiled "Project Voldemort" dossier of Facebook's hardball tactics fed to the FTC in 2019 — and it predates the European Commission's formal probe into the online classifieds market and the UK CMA's parallel preparation announced in 2021.
What changed with this story is the depth of the inquiry: EU investigators moved from screening allegations to demanding internal Facebook documents specifically about leveraging access to user data against potential rivals, which is the evidentiary groundwork for the statement of objections over Marketplace that Politico later reported regulators were preparing to send.
First-order effects
- Facebook is compelled to surrender internal documents to EU investigators, exposing internal decision-making about data access and rival treatment to regulatory scrutiny for the first time in this case.
- The investigation's focus narrows from general dominance concerns to a specific conduct theory — using privileged user-data access to stifle nascent competitors — which Facebook must now answer with evidence rather than policy arguments.
Second-order effects
- The UK CMA's preparation of its own data-leveraging investigation signals parallel proceedings, meaning Facebook faces duplicative discovery and cannot settle its way out in a single jurisdiction.
- Rivals in classifieds, social media, and online ads gain a documented regulatory track to attach their complaints to, lowering the cost of escalating from private grievances to formal evidence submissions.
Third-order effects
- If the document trail supports the allegations, the case points toward formal charge sheets and conduct remedies targeting data access itself — making user data a regulated competitive asset rather than a proprietary one.
- The EU-UK-US sequencing (Commission, CMA, FTC all working the same conduct theory) suggests platform data-leveraging becoming a standardized antitrust template applied across jurisdictions, with the strictest regime effectively setting the global rule.
The trend: Competition regulators on both sides of the Atlantic are converging on user-data leverage as the core theory for policing platform gatekeepers, moving from rival complaints to document-level investigations and formal charges.
