The states, with a few exceptions like Texas, took the money and ignored the consequences. Like the mafia, once you take the money from the feds you have sold them your soul. I have worked in agencies that were started with promises of 90-100% reimbursements by the feds and eventually the reimbursements are significantly reduced or eliminated. But, all the strings that come attached never go away. This has been the feds' modus of operendi for over 70 years, it has just become more blatant in the past 20. The states are stuck. You either do what the feds say or they starve your other programs and what state politician wants to be known as the guy that lost billions to a neighboring state. That's the game, the Constitution is not a thought.
