> Is there collateral damage when forks like this happen? In this specific case, the only collateral damage would be if the attacker used the produced bitcoins to pay someone, and received something in exchange for this. In this case, whoever sent the attacker something in exchange for the bitcoins, would stand empty-handed after these bitcoins ceased to exist.
