who will be held liable for bitcoin programs errors

so there was the Value overflow incident in which nearly 200 billion bitcoins are created; while the problem was fixed promptly, it introduced a fork where people receiving money on the stale fork might suffer financial loss; but bitcoin is decentralized so who would be held liable for such loss? the software author? the bitcoin inventor? or nobody? do users get acknowledged before they start using bitcoin that such bugs may happen and must accept a liability disclaimer to use bitcoin?
