The U.S. Federal Trade Commission (FTC) has addressed concerns to the CEOs of major financial service companies, including Mastercard, Visa, PayPal, and Stripe, regarding the potential denial of services to customers based on political or religious beliefs. The letters warn that such practices could lead to investigations and enforcement actions. This initiative follows an incident involving Valve, where Mastercard was alleged to have pressured the company into removing adult-themed games from its Steam platform, although Mastercard clarified it did not directly influence the removals. FTC Chairman Andrew N. Ferguson emphasized the importance of ensuring all law-abiding individuals can engage in commerce. The situation is further complicated by an executive order from former President Donald Trump, which raised concerns about financial institutions surveilling individuals involved in conservative activities. Ferguson urged Mastercard's CEO to prevent unlawful debanking practices by its network members. There is uncertainty regarding a proposed rule change that may not significantly alter the discretion financial institutions have in customer-related decisions. Inquiries have been made to Valve and the FTC about the implications of these letters for adult video games on the Steam platform.
