They failed something through a fault in the game, not their own. The same as failing any missions due to a bug. How is that entitlement? It's the fault of FD. The game didn't work as it is supposed to, causing a failed mission.
Because they are asking for the money for the missions, on the assumption they would have succeeded.
They have invested Zero CR in the cargo, so there is no loss to their credit balance, only a loss of potential earnings BUT those potential earnings were not guaranteed, as they might have failed the missions normally.
That they could have still failed the missions normally invalidates the argument it was their time lost, unless you are saying they would have argued failing the mission normally would also be a waste of their time deserving compensation.
