The question you should be asking is what they did to ALLOW that theft in the first place, and who gave them the authority to unilaterally change the blockchain, which was previously understood as an irrevocable ledger of transactions? ETC was not the fork, ETH is the fork. ETC was exactly the same thing before and after the fork, except in name. The developers of ETH could have prevented the fork by allowing losses to be born as a result of the faulty DAO code, as would happen in any other free market system thus incentivizing developers to create better code and investors to vette their investments more carefully. Instead they chose to save their own personal investments, and a handful of other large investors, at the expense of all ETH holders. Welcome to cryptosocialism.
