Spotify has criticized Apple for imposing up to a 27% fee on transactions in the US when developers use alternative payment options outside of Apple's App Store.
Apple recently allowed developers to direct customers to other payment methods, but still demanded a commission.
The music streaming giant called the charge "outrageous" and accused Apple of fiercely guarding its profits, urging the UK to block similar charges.
After a legal dispute with Epic Games, Apple lost on one count, forcing it to allow developers to inform customers of non-App Store payment options, while still charging a significant fee.
Apple insists the fee complies with the court ruling, claiming developers gain from its platform's integrity and services, including marketing and a secure environment for app downloads and purchases.
Spotify has strongly opposed the policy, claiming it undermines US court efforts to promote competition and has a long-standing grievance with Apple's control over the internet.
Spotify is now calling on the UK government to act through its forthcoming Digital Markets, Competition and Consumer Bill to prevent Apple from imposing similar fees, aiming to foster a competitive tech landscape.
The UK's bill seeks to reign in tech giants' power, with measures specific to app store transactions under consideration. However, the UK government has not committed to any action against Apple in response to the bill.
