YONHAP - Aug 3 - A U.S.-based group of companies that has voiced opposition to commissions major app stores collect from developers expressed support Tuesday for legislative movement in South Korea to pass a bill that seeks to curb the so-called app store taxes. Last month, the National Assembly's Science, ICT, Broadcasting and Communications Committee decided to approve amendments to the Telecommunications Business Act, which seeks to ban app market operators from forcing certain payment systems on developers by unfairly using their position. The bill, which would be the first of its kind globally if voted into law, currently awaits further review by the Legislation and Judiciary Committee before being handed off for a wider vote by the National Assembly. Mark Buse, Match Group's senior VP and a founding member of the Coalition for App Fairness, met ruling Democratic Party lawmakers at the National Assembly in support of the bill. The U.S.-based group consists of major tech companies, including hit video game "Fortnite" maker Epic Games, music streaming giant Spotify Technology SA and Match Group.
