It's actually the fault of both Mastercard/Visa/Stripe as will as OSA and Collective Shout. They are the ones ultimately making the decisions and no where is safe as long as they have a say in what sites sell.
People have been posting a lot of helpful links and phone numbers to call in other discussions but I will add a couple here:
UK petition to repeal OSA: https://petition.parliament.uk/petitions/722903
US ACLU petition against Mastercard: https://action.aclu.org/petition/mastercard-sex-work-work-end-your-unjust-policy
If you call Mastercard, Visa, and/or Stripe: be polite but assert that you will not do e-mail. They want you to do emails right now so they can easily filter and ignore them. Calling hits them the most. Here is a Bluesky thread from someone that worked at a call center.
