We have seen the hacking attack of reportedly 60M USD from Bitfinex and the attack of the DAO for reportedly around double that amount.
But after both attacks we have seen two very different things happen.
In the case of the Bitfinex attack there isn't even the slightest suggestion that some sort of "hard fork" would be offered by the Bitcoin Core developers (so they are just going to have to wear their loss for their mistake) but in the case of Ethereum we have now ended up in a "fork war" with ETH vs. ETC (and ironically ETC is actually the "original" code with ETH now being a fork).
Opinions?
Fortunately, I think this has set the fork-at-any-cost camp back in a huge way. I think they realize that their only chance to get big blocks is to fork without any suggestion of majority or consensus. I think some of the more extreme big-blockers see the viability of both ETH and ETC as a reason to say "let's fork and let the market decide." Terrible idea, but there will always be some around here who are willing to break consensus for their agenda.
