It’s no secret European bureaucrats aren’t fans of American Big Tech. Now, some American lawmakers are crossing party lines to steal pages from their playbook. Sens. Chuck Grassley (R-IA) and Amy Klobuchar (D-MN) recently reintroduced the American Innovation and Choice Online Act, which revises a 2022 bill that stalled in the Senate. Like the European Union’s Digital Markets Act, it purports to stop large digital platforms like Amazon, Meta, Google, and Apple from harming consumers and the businesses that use their platforms to reach them. Instead, AICOA would police many conventional business practices that generally benefit both consumers and business users.

​

U.S. antitrust law already punishes “monopolization,” or a firm’s abuse of its market power to exclude competitors and harm consumers. Since some practices that improve products or lower costs can also “exclude” a firm’s competitors, antitrust courts apply the “rule of reason” by weighing the pros and cons of a practice in each case before penalizing defendants. This has created legal precedents that give businesses clarity about whether they are likely to face antitrust litigation or liability under some general “standards.”

​

Unlike bright-line rules, standards require more time and resources to enforce. However, blanket rules can outlaw practices that are pro-competitive in many cases. Successful rulemaking requires cautious fine-tuning to ensure alignment with policy goals. Conversely, U.S. antitrust standards become consistently understood over time as courts apply the same principles to similar cases. For instance, the same principles applied in 2001 to resolve whether Microsoft engaged in anticompetitive behavior by making Internet Explorer the default browser in Windows were recently used to resolve whether Google illegally excluded rivals by contracting with web browsers to become their default search engine. This approach combines flexibility and pragmatism with comparable certainty and predictability to a “rule.”

 

Take Google Maps. It is integrated with Google Flights and Google Hotel Ads, giving Google an advantage in search results over other flight and hotel aggregators like Expedia and Booking.com. However, the integration also fosters seamless search and booking experiences, which benefits users and pressures competing aggregators to offer greater value. Though currently legal in the United States, the DMA bans this integration with a blanket “self-preferencing” rule. The result? Hotel and flight bookings in Europe take far more clicks, costing consumers nearly $4 million in quantified wasted time yearly. The degraded user experience also drove a 30% loss in web traffic and a 36% loss in direct bookings on Google Hotel Ads, harming smaller hotels reliant on the service.

​

Instead of learning from Europe’s mistakes, AICOA would import them. Like the DMA, it targets various product integrations deemed to disadvantage the digital platform’s competitors, including cross-use of data between services, self-preferencing, and restricting competitors’ use of certain platform features. 

​

AICOA’s proponents argue it maintains antitrust law’s “standards”-based flexibility. Unlike the DMA’s blanket bans, which are enforced by regulators with only narrow exceptions, competition enforcers must take firms to court for AICOA violations. Defendants can argue the practice does not “materially harm” competition, or is necessary for user privacy or security. 

​

However, these differences are a veneer. “Materially harm competition” is a vague term, undefined in prior cases. AICOA describes it as “any actual or reasonable risk of lessening of competition … that is more than a de minimis amount.” This low bar prevents a holistic weighing of pro- and anticompetitive effects, advantaging competitors seeking a shield from competition rather than helping consumers. Affirmative defenses must also be proven by “clear and convincing evidence,” which is hard when the impacts of a novel or new technology, product integration, or business practice may not yet be clear, or when a counterfactual without the integration cannot be reconstructed. By creating substantial uncertainty and litigation risk, both AICOA and the DMA raise compliance costs and risk chilling experimentation and innovation that benefits users and small businesses alike.

​

These harms aren’t theoretical. Uncertainties about what DMA compliance requires and how to balance compliance with privacy and security caused delays of up to a year before cutting-edge AI features including Apple Intelligence, auto-translate for AirPods, and Google search AI summaries reached EU users. A recent survey finds that EU and U.K. small tech firms forego approximately $109,000 to $375,000 per year due to delayed product and AI model launches. Almost 60% of U.K. and EU developers report launch delays, and over a third had to downgrade or cut features to comply. Studies estimate an AICOA-like policy could similarly cost American SMEs billions.

​

America’s world-leading tech sector emerged from vigorous competition and innovation under laws that generally favor commercial experimentation instead of punishing firms for their size, efficiency, or success. Europe has struggled to produce leading technologies and platforms despite its skilled and educated populace. Burdensome regulations that leave small and large tech firms in the dark without concomitant benefits don’t help. Just half of European startups actively use artificial intelligence today, compared to almost two-thirds in America. Importing their policy failures isn’t just unwise. It’s un-American.

Setting It All Ablaze: John Howard's 1998 Letter to B.J. Habibie

This essay was written for the 2024 YRIS High School Competition. Contextualizing John Howard's 1998 letter, I argue for a pragmatic view of foreign policy in which instability like that of Howard's actions may be a "necessary evil" to achieve long term peace. This essay received an Honorable Mention (Top 5) and was published on the website of The Yale Review of International Studies.
