they're a bunch of bullies who try to get rid of everything they don't like and scare companies like payment processors into forcing other companies to remove the stuff they don't like or remove their services, their "open letter" has is titled "Open letter to payment processors profiting from rape, incest + child abuse games", they are the kinds of extremists that equate fiction with real life and just harm the creative industry, I'd say using reductive language towards this group is fine
