Major payment processors like Visa and Mastercard have been accused of pressuring storefronts to remove adult games from their platforms. However, both companies claim they did not pressure Steam or its competitors directly. Instead, they say other payment processors communicated the issue to them. Collective Shout, an activist group, has acknowledged influencing actions taken by Valve and itch.io, but denied asking for all NSFW games to be removed. The controversy raises concerns about censorship and the impact on game creators. Some platforms, like GOG, have responded by making adult games available for free, while others, like Zoom, are exploring alternative payment options to avoid censorship.
