it's not necessarily about the car company
You. And the unlucky renters. Should ask about the credit they used, and what the terms of the car rental insurance protection is. And whether there is such protection. And if there is such protection, whether that protection applies to the Dominican Republic. Some card companies limit the protection based on the number of days the car is rented, or the time of year. You have confirm all of the terms and conditions and you shouldn't assume the terms and conditions don't change from month to month. Sorry to hear about what happened. In case you haven't already, you should get your friends to dispute the charge. If nothing else, it could give them more time to pay the fee before the interest starts to kick in.
