I have a basic question which I haven't been able to find the answer to. When ETC forked from ETH, anyone who was holding ETH automatically had an equivalent amount of ETC in the ETC chain. They did not have to enter their private key or import their passphrase (ETZ - like really??) anywhere. Why is ETZ any different? This sounds super shady, but if there is a technical reason behind this need, I am interested in knowing.

Thanks!
