The ongoing legal battle between Apple and Epic Games has taken a new turn as Epic requests federal intervention, accusing Apple of not adequately removing anti-steering measures. Meanwhile, a separate feud between Epic and Valve has surfaced, with Epic CEO Tim Sweeney's emails to Valve's Gabe Newell, calling Valve 'assholes' over Steam's policies, particularly its 30% revenue cut. These emails have come to light in a lawsuit, revealing an exchange where Valve's COO responded with 'you mad bro?' to Sweeney's complaints. Additionally, Epic is challenging Apple's 27% commission on website purchases in court. The disputes highlight the tensions between major tech companies over platform fees and policies, impacting startups' ability to innovate due to the industry-wide 30% tax.
