If itch doesn't want to fight for creators than their cut is 0% simple.
Viewing post in Genuinely go fuck yourself itch.io
So you would have rather itch put out a brutally honest message like this: "We really want to keep fighting for you. But there is a high chance that Visa and Mastercard will drop support of our site, depriving us of the revenue and payment options that are desperately needed to keep Itch.io afloat." Followed by a plea of financial support through means other than Visa or Mastercard.
Thing is Itch did far more than just remove "Obscene" content as far as the Comstock act and the payment processors are concerned. They actively went above and beyond and fucked over so many more people than required, and for what? To show groups like collective shout that they're willing to toss their own userbase and customers under the bus? Itch can get fucked, frankly.
When fuckheads try to dick you around you fight back, period.
In this scenario the best case option is they back down and fuck off. The worst case option is itchio fucks them off and uses other payment processors.... you're weighing the "pain" of users having to go and sign up to a different payment processor vs letting a third-party abuse their power to dick you around and decide your rules like they own the place.
