It does not matter if somebody voted for the wrong witness accidentally or intentionally. It caused the same amount of damage that can never be undone.
We have the power to forgive these people, but we can never undo the mess caused by those who supported Justin Sun's actions.
I agree each of these accounts should be weighed individually, and not massed together to decide if they should all receive an airdrop.
Personally I chose to boycott steemit and all its primary interfaces as soon as Hive became an option, and I am suspicious of anyone still investing time, energy, and funds in steem. I consider it a competitor that is still actively trying to shut us all down. In this case, I do not support anyone trying to serve two masters.
Some people thought it would help peaceful resolution by supporting witnesses on both sides, and look at how that worked out. This is a case where you don't want to be on the losing side, or neutral side of a war, because you are attributed the blame of the victors.
Let's say steem shut down, what will be the Fate of those who didn't get the Airdrop and spent couple years trying to make steem an income? (voted on sock puppet accidentally or on purpose).
I would say it's too late to sue for damages.
