On the one hand: Absolutely I agree! Itch got this basically dropped on them with little to no notice, and did what they had to in order to keep the lights on. This has been a problem that has been handled by various platforms in the past (Patreon went through somethin' similar a few years back) and Adult Entertainment sites have been taking people's money since the internet existed. This is a minor, temporary problem that we don't need to freak out about, and I suspect most people won't remember what the big deal was this time next week.
On the OTHER Hand: This KEEPS HAPPENING. The number of times payment processors have pulled the rug (or almost pulled the rug) out from a major site, causing its adult content creators to flee or panic, has gotten ridiculous. People are going to forget this happened in 1-2 weeks, and then some OTHER place is gonna get hit. And it's gonna keep on getting hit. Get mad! Fight the power! etc. etc.
