Stop Killing Games has thrown its weight behind a Dutch consumer lawsuit accusing Sony of abusing monopoly power through the PlayStation Store's pricing stranglehold. The group joins Does It Play? in backing Stichting Massaschade & Consument's case, which targets what critics call the "Sony Tax" — a markup that allegedly inflates digital game prices by up to 50% compared to physical retail, all while locking out competing storefronts.

The suit, filed on behalf of roughly 1.7 million Dutch PlayStation owners, seeks up to €400 million in damages and traces its roots to 2024 but gained fresh momentum after Sony confirmed plans to end physical disc production by January 2028. Without secondhand markets or alternative sellers, advocates argue Sony gains unchecked control over both price and access, a point Stop Killing Games highlights as it pivots from its stalled European preservation push into broader consumer advocacy.

Riley's receipts show the case centers on Sony's 30% commission and closed ecosystem rather than game shutdowns themselves, though the timing with the disc phase-out is no accident in the plaintiffs' view. Dutch courts at the District Court of Midden-Nederland have already heard opening arguments, and similar anti-competitive claims against Sony's store model are bubbling in other countries. PC storefront owners are likely watching closely — Valve has faced its own Steam cut litigation for years.

The move signals Stop Killing Games expanding its mandate after setbacks on EU legislation and a California bill, folding preservation concerns into wider fights over ownership and pricing. Whether the suit lands refunds or forces structural change remains to be seen, but the paper trail on Sony's digital lock-in is growing longer.
