EU Moves Beyond Fines to Force Structural Changes on Big Tech

The European Commission is transitioning its enforcement strategy against Big Tech, moving from a reliance on financial penalties toward direct structural mandates. This shift comes as the first wave of major cases under the EU's digital rulebook concludes, signaling a new phase of regulatory pressure on global technology firms.

Brussels recently imposed approximately €890 million in penalties on Google for breaches of the Digital Markets Act (DMA). According to regulatory filings, the total is split between a €460 million fine for self-preferencing in search results and a €430 million penalty for restricting app developers from promoting external offers within the Play Store. Beyond the fines, the EU has ordered the U.S. search giant to overhaul its search result rankings for rivals and reform its app store policing mechanisms to avoid further sanctions.

The Regulatory Backdrop

This escalation is part of a broader effort by the EU to curb the dominance of so-called "gatekeeper" platforms through the Digital Markets Act (DMA) and the Digital Services Act (DSA). For years, the European Commission pursued Big Tech through traditional antitrust litigation, which often resulted in multi-billion euro fines. However, these financial penalties were frequently viewed as a cost of doing business rather than a catalyst for systemic change. The current framework is designed to prevent self-preferencing and foster a more open digital ecosystem by establishing proactive rules that companies must follow to maintain market access.

A Shift in Enforcement Logic

The move toward structural mandates indicates that the EU is no longer satisfied with retrospective fines. By requiring fundamental changes to how core products—such as search algorithms and app store policies—are engineered, Brussels aims to permanently alter the competitive landscape. This approach forces companies to modify the actual architecture of their services, which has a more immediate and lasting impact on smaller European rivals than a one-time payment to the Commission.

Future Implications

Industry observers are now watching to see how other designated gatekeepers will respond to this more interventionist style of policing. The focus has shifted to whether these structural overhauls will effectively lower barriers to entry for competitors or if companies will find technical workarounds to maintain their dominance. As the Commission continues to implement the DMA, the benchmark for compliance is moving from legal arguments over past behavior to the technical verification of product changes.
