The Stop Killing Games movement has joined a $457 million lawsuit against Sony brought by Dutch consumer group Stichting Massaschade & Consument, accusing the PlayStation maker of running an unlawful "monopoly" over digital game pricing. The action forms part of a wider backlash against Sony's decision to end physical game production from January 2028, a move that has fuelled concerns about ownership, competition and pricing in an all-digital games market.

The Dutch group originally filed its lawsuit in February, alleging Sony artificially inflated PlayStation Store prices for Dutch customers and demanding repayment of an amount it says runs into hundreds of millions of euros; Stop Killing Games, which has gathered over 1.2 million petition signatures since forming in 2024, is now backing the case and branding the markup a "Sony Tax". It is one of several legal challenges facing Sony, alongside a UK class action filed in March, a US tariff-related refund lawsuit from May, and a complaint lodged by Mexican lawmakers with the country's antitrust regulator. Sony has shown no sign of reversing its physical-disc decision, with CFO Lin Tao telling investors the company intends to "cautiously move this forward".
