The ETC price is dropping at the moment, if the trend continues, by the end of August, the DAO hacker will not earn much.
Some ETC holders are very rich, they own a lot of bitcoins. So they might be able to support the price after the dump.
So let them do that. I think the Ethereum Foundation should sell its ETC at the current price to support the development of ETH.
The ETC has already declared independence. So it has its own community and its community will support its development.
Does not mean that the Ethereum Foundation will not support the ETC developments in the future?
The Ethereum Foundation will have nothing to do with the ETC. The ETC can copy the code if it wants to do. That will be a clone.
