Would itch consider switching to a different payment processor? While companies like Stripe are the biggest, there are many others out there that came about after censorship groups pressured payment processors into going after others in the past, e.g., electronic repair communities, and communities developing 3rd party schematics.
Given how much more effective these censorship companies are becoming, my may be best to just move to a payment processor whose business model is to never ban any legal content. If itch sticks with their current payment processor, they will only continue to gradually censor more content and this situation will become a regularly occurring event.
