It was a big mistake.
But Ethereum is still the leader in terms of a lot of technical aspects and also the ability to pull people together.
To try to give people a perspective: say you and your friends took out second mortgages on your houses and came up with 5 million to invest. Then you invented some tool, and someone found a back door or bug in this tool that allowed them to steal 1 million dollars.
So most of the group would like to undo this 1 million dollar theft with a patch.
Now, most outsiders are condemning you for trying to work around the bug and recover your million dollars with a patch.
I think that the mob is fickle. Quick to pile onto a bandwagon, and quick to burn it.
So, I hope Vitalik and the other group of hard working, intelligent and ethical people involved do not take the mob's response to heart.
