A South Korean parliamentary committee voted on Wednesday to recommend amendments to the law that could ban Google and Apple from forcibly charging software developers a commission. If the amendments are passed, this will be the first such restriction by a major economy and could hit these companies hard. And other countries can follow the example of South Korea.

Apple and Alphabet have long been criticized for their policies: the companies require software developers using their app stores to use only their own payment processors, which charge fees of up to 30%.

Apple said the new law would «expose users who purchase digital goods from other sources to the risk of fraud, undermine their privacy protections,» undermine user confidence in app store purchases, and reduce opportunities for South Korean developers. Wilson White, Google’s senior director of public policy, said the company didn’t have time to analyze the negative impact of the law on Korean consumers and app developers.

«Google and Apple are not the only ones who can create a secure payment system,» said Lee Hwang, a law professor specializing in competition law at Korea University.

The proposed amendments would bar Google and Apple, which dominate the market, from imposing payment systems on content providers and «improperly» delaying review or removal of mobile content. The law also allows the South Korean government to protect the rights and interests of users, verify app marketplace operators, and resolve disputes regarding payment, cancellation, or refunds in the app marketplace.

After the approval of amendments to the law, dubbed the «Law against Google», these changes are submitted to the final vote in Parliament, which will be held on August 30.
