That's kind of like the trope of a loan shark "busting people's legs". It doesn't do any good, because then they can't work to make the money they need to pay off the loan shark.
Threats only work if you carry them out when someone calls your bluff. The loan shark is interested in making sure everyone else pays.
There is a 5-year contract in place, so a little different than just a credit card on file that is failing to charge based on usage. Also, it was reported they aren’t using the compute power as expected in contract, so the bill may not fully relate to actual resources consumed.
just revoke their account and wipe their databases :-) like every other account that's behind on their bills
