> Lastly, if they'll fork for one bad contract, why not fork for all bad contracts? Conceptually, they would, it's just that DAO was an exceptional case. a) The amount was really large. b) Ethereum ecosystem wasn't mature enough (and yesterday's event proved that they can take a hit like that and survive). c) DAO had a 30 day lockdown of the hacker's fund, this is something which allowed for a hard fork to be possible. The last is really important. Once hacker gets your money out of the hacked contract, no hard fork is feasible. The DAO essentially created a situation where it was impossible for hacker to get the money, nor for the white hat hackers to get the money. Both could have created a script, where hacker would move his funds to a new child contract, and the WHG would follow him to the child contract (thus essentially rendering him unable to get his money out).
