I don’t know the details of your contract - clearly you think it gives them an escape clause. Most agreements have a term and a termination component. I am aware of the unreliability of politicians but this is our government. The insurance companies have a case imo. They were induced to offer insurance policies they didn’t want to offer on the promise of reimbursement for a period of X (3?) years. They did their end of the deal, they should be reimbursed.
This doesn’t mean I like the deal or the ACA, only a question of being honorable to the word of the deal.
The newspapers say the 30,000+ moms, babies and disabled have been thrown off Medicaid in GA when they had contracts with GA to received Mecdicaid. Should we apply welfare to the rich and welfare to the poor equally? Of course, the reality is that one group has a better set of lawyers.
