Valve is facing a class action antitrust lawsuit over its 30% Steam sales commission, with developers alleging anti-competitive practices. Valve has defended the commission as an 'industry standard,' though competitors like Epic Games and Microsoft charge significantly lower rates of 12%. Meanwhile, Apple is embroiled in multiple legal challenges concerning its App Store commission fees. In the UK, Apple faces a £785 million class action lawsuit led by competition policy expert Sean Ennis, accusing the company of imposing an anti-competitive tax on developers through fees of up to 30%. A $995 million lawsuit related to the same issue has been allowed to proceed after Apple failed to block it. Additionally, Apple faces a $1 billion class action lawsuit over the same issue. Separately, Apple and Epic Games are set to appear before a US Magistrate Judge in San Francisco for a discovery hearing, with Epic accusing Apple of violating a court order regarding its App Store operations.
