Recently, both Steam and Itch.io caved to pressure from payment processors and removed NSFW and "adult" games, or made them harder for players to access. Itch appeared to go even further than Steam in its response with a broad list of "prohibited themes" and got a lot of pushback; now the indie storefront says it will be looking for new payment partners.
Itch added an update to its earlier statement regarding these payment changes, spotted by Rock Paper Shotgun: "We are actively reaching out to other payment processors that are more willing to work with this kind of content. We have suspended the ability to pay with Stripe for 18+ content for the foreseeable future."
