Without an idea of what it is that you are selling it is impossible to say whether or not you or Stripe are in the right here. Given that Stripe is willing to refund your customers that indicates that they do not want to be party to these transactions, you can then of course ask your customers to send you payment through some other means.

If you've shipped the goods before you received the payment that was a risk that you took upon yourself. If Stripe kept your money and did not refund your customers I would say the situation would be much more grave but apparently that did not happen.

You write 'If the payments do end up being refunded, we will of course be taking legal action and contacting media outlets in efforts bring this story to the public eye, and to hold Stripe accountable for this' -> but that's the wrong order. You've already been warned that Stripe will refund the customers. If you don't want that the time to take legal action is now and the first thing to do is to put a pre-emptive hold on that action until a judge has spoken about whether or not the refund can go through. Allowing the refund to go through without taking legal action is - pardon my French - about as stupid a move as you could make at this point.

Go talk to your lawyer, pronto, and stop making things worse for yourself by letting the clock run out.
