On 31 August 2021, South Korea passed the world's first ‘IAP Act’ that bans mandatory in-app purchases. Mandatory in-app purchase is a policy by Google and Apple, which monopolise the mobile application market, to force consumers to pay only through their payment systems. This policy has been criticised as unfair because it involves a commission fee of up to 30 per cent. In the meantime, Google announced their policy to expand the mandatory in-app purchase and 30 per cent commission fee that was previously only applicable to games to other digital content areas such as webtoons, music and e-books, and this is how South Korea’s legislation was made, to protect consumers and safeguard the application ecosystem from the big tech's monopolistic dominance.
