Just want to leave people with a bit of hopeium but itch is currently looking for payment processers outside of the ones currently forcing the deindex according to an addendum in there NSFW content post quote,
"In the meantime, 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. Our immediate focus has been on content classification reviews and implementing stricter age-gating on the site."
If these payment processers can be reached and work with itch then MAYBE this will make it harder for some outside Christian conservative fake feminist morality police group to censor games on the site, though the content moderation may get stricter.
Just looking on a potential bright-side
