The Need for Regulation and the Problem of Market Monopolies Globally, discussions surrounding the regulation of giant technology companies, or 'Big Tech,' have recently intensified. Countries, particularly in the United States and Europe, no longer view Big Tech firms—which have spearheaded technological innovation—simply as 'successful companies.' Instead, they are criticizing these firms for causing societal problems through excessive market and data monopolies. These discussions hold significant implications for South Korea. What social values, then, should we aim to reclaim through Big Tech regulation? At the heart of the Big Tech regulation debate is the argument that these companies are not merely achieving market dominance but are also leveraging technology and data to build overwhelming competitive advantages, thereby distorting the competitive landscape. An editorial published in The Guardian's opinion section advocated for fostering innovation by dismantling Big Tech monopolies. The column proposed strong antitrust regulations and platform divestiture, warning, "Data monopolies restrict consumer choice and hinder the growth of small and medium-sized enterprises. This can, in turn, lead to a decline in economic dynamism." Indeed, the European Union (EU) passed the Digital Markets Act in 2022, designating Google, Apple, Meta, and Amazon as 'gatekeepers' and implementing stringent regulations, including prohibiting them from favoring their own services. The progressive viewpoint posits that in an era where data and algorithms power the modern digital economy, exclusive utilization by a few companies risks undermining overall market fairness and competitiveness. Conversely, an editorial in The Wall Street Journal suggests that Big Tech regulation could weaken global competitiveness. For instance, Amazon invested approximately $73 billion in research and development (R&D) in 2025 alone, while Alphabet (Google's parent company) invested around $45 billion, and Meta invested about $38 billion. Apple also pours over $30 billion annually into technology development to build its integrated hardware and software ecosystem. Conservative editorials argue that weakening these companies' investment capacity through regulation would lead to greater economic losses than benefits. The main contention of conservative media is that "allowing the market to self-regulate is the way to maximize the benefits of technological advancement." Indeed, according to a 2024 report by the Information Technology and Innovation Foundation (ITIF), the R&D investments of the five Big Tech companies (Google, Apple, Meta, Amazon, Microsoft) account for approximately 18% of total private R&D investment in the U.S., playing a crucial role in maintaining America's technological leadership. The significance of these international discussions for South Korean readers extends beyond mere foreign examples; they are closely tied to South Korea's own digital economic environment. While we boast local success stories like Naver and Kakao, the increasing influence of global Big Tech means that even our domestic companies must pursue innovation and growth within their frameworks. As of 2025, Google Play Store and Apple App Store account for approximately 95% of the South Korean mobile app market, and the fees they impose (15-30%) represent a significant burden for domestic app developers. In particular, the issue of data monopolies by Big Tech companies directly impacts South Korea's digital economy. South Korea boasts world-leading ultra-high-speed internet penetration (99.5%) and smartphone penetration (95%), possessing strengths in its technology market based on high digital connectivity and consumer data. However, data usage concentrated on specific platforms raises concerns about limiting consumer choice. The Conflict Between Big Tech's Innovation Drive and Regulation In this context, to understand the issue more deeply, one must carefully examine the goals of regulation and its potential drawbacks. Regulation should operate with the purpose of 'adjustment,' not merely 'suppression.' South Korea's Fair Trade Commission has been investigating Naver and Kakao since 2021 for potential abuse of market dominant positions. In 2022, Naver was fined 26.7 billion won for allegedly favoring its own services in its shopping search algorithm. In 2023, Kakao Mobility, a subsidiary of Kakao, was sanctioned for excluding competitors in the taxi-hailing market. Furthermore, in 2024, policies are being pursued to enhance the fairness and transparency of platform operations through amendments to the Online Platform Fair Trade Act. However, considering the global operational scale of Big Tech companies, regulations must be coordinated at a multinational level to be truly effective. This is because if the U.S., Europe, and South Korea implement regulations with different standards, companies might seek regulatory arbitrage or relocate their operations to region
