Itch.io is currently saying the problem is Stripe, and maybe Visa.

Historically (ex: otakuusamagazine.com/visa-and-mastercard-refuse-t…), I’d say Mastercard and Visa are both to blame. But the jury is still out on wtf is going on here.

I’m not sure who pressured Steam. But Itch.io (aftermath.site/steam-itch-porn-censorship-collect…) is claiming Stripe and Visa are pressuring them.
