If they don't then they are black hats themselves. Personally I would destroy them, tipps to the Grey.
Not really,
As long as "The DAO" uses those ETC to increase the price of the tokens or increases the price of ETH (fork supported by the Ethereum Foundation) then they've actually fulfilled their mandate to maximise value for their investors.
Because the benefit of such an operation, would be for the investors in "The DAO".
Obviously, this may be bad news for people who want ETC's BTC price to climb rapidly.
