South Korea’s media regulator has fined Google 42.9 billion won, about $32.35 million, and Apple 20.8 billion won for limiting users to specific app payment systems, and has ordered both companies to take corrective measures. The decision, announced on Wednesday, is the latest regulatory challenge to how the two largest app store operators control payments inside their stores. The fines are modest against either company’s revenue, but the order to change payment practices carries wider significance.
What The Regulator Ordered
South Korea’s Media and Communications Commission said Google and Apple restricted users to particular payment systems, limiting choice for app users and developers. Google’s fine of 42.9 billion won converts to about $32.35 million at the rate of 1,326.09 won to the dollar, while Apple’s 20.8 billion won fine is worth roughly $15.7 million on the same basis.
Alongside the fines, the commission ordered corrective measures, though the regulator’s statement as reported did not detail every step the companies must take. The order matters as much as the money: fines of this size are small against either company’s revenue, but a binding instruction to change payment practices can reshape how apps charge users in a major market.
Apple said it disagreed with the decision and was evaluating its options in accordance with South Korean law, adding that it had worked with outside developers to enable innovation through its App Store. Google did not immediately comment when contacted, leaving its response to the order unclear for now.
Why App Payments Keep Drawing Regulators
App store payment rules have become one of the most contested questions in technology regulation worldwide, because the store operator typically takes a commission on digital purchases made inside apps. Developers argue that being forced into one payment system raises their costs and limits alternatives, while store operators say the system funds security, review and distribution.
South Korea has been an early mover on this question, and regulators in other major markets have since pursued similar cases against app store rules. Each national decision adds pressure, because a company that changes its payment system in one country faces questions about why the same change should not apply elsewhere.
The case also lands as platform regulation spreads beyond app stores into AI and content, as shown by the delay to Meta’s new AI content terms after publisher complaints. Regulators are increasingly treating large platforms as infrastructure whose rules affect whole industries, not merely as private marketplaces.

What Happens Next
The immediate question is whether either company appeals or negotiates the corrective measures, and how quickly users in South Korea see any change in how they pay inside apps. Apple’s statement that it is evaluating options suggests a legal challenge or a negotiated adjustment is possible, rather than immediate compliance in full.
Developers in South Korea will watch the corrective measures closely, since the practical value of the decision depends on whether alternative payment systems become genuinely usable, rather than merely permitted on paper. A remedy that leaves the store’s own system as the default may change little in practice, however strong the headline fine appears.
For Google, the fine adds to a series of regulatory pressures on its app business, even as it expands its consumer AI products, including the Chrome autofill upgrade that draws on Gmail. The company must now weigh the cost of fighting the order against the precedent that compliance would set in other markets.
Why It Matters
The sums involved are modest, but the principle is not: if regulators can order the world’s two largest app store operators to open payment choice, the model that has funded app distribution for more than a decade starts to loosen. Developers gain leverage, users gain options, and store operators lose a measure of control over their own ecosystems.
The case is also a reminder that regulation now moves on several fronts at once, from app payments to AI safety rules such as Australia’s new digital duty of care. Companies that once dealt with regulators one market at a time now face a pattern of parallel challenges across countries and technologies.
Background
South Korea’s regulator has previously scrutinised app store payment practices, and the latest fines continue a multi-year effort to give users and developers more choice over how digital purchases are paid for.
