In a significant development in the ongoing legal battle between Epic Games and Apple, several major tech companies, including Meta, Microsoft, X (formerly known as Twitter), and Match Group, have joined forces with Epic Games. They accuse Apple of not complying with a court-ordered injunction that mandates allowing alternative payment options within its App Store. This collective action was formalized through an amicus brief filed in the Epic v. Apple case, as reported by the Wall Street Journal, expressing opposition to Apple's plan to impose a commission on payments made outside the App Store's traditional mechanisms. The companies argue that Apple's actions violate both the letter and spirit of the court's order, undermining efforts to open the App Store to outside payment options. This legal alliance highlights the industry-wide implications of the dispute, emphasizing concerns over Apple's handling of App Store fees and its adherence to the California anti-steering order, despite similar commission practices by Microsoft and Epic themselves.
