Patreon intends to keep your $8,000? That has to be basically criminal, doesn't it? That's your money, we didn't intend to give that to Patreon!
Unfortunately I believe I cannot support you on SubscribeStar, as it does not allow PayPal or iDeal or any of the typical payment options available in my country (the Netherlands), where we don't normally have credit cards. Unless I'm missing something! So I'm a little worried what this change will mean for my ability to continue to play your game, nevermind support you further, which I would like to do.
EDIT: Found a link you shared in another comment, but it seems to be talking about prepaid/virtual cards, and I have some bad experiences with those… darn.
