Well they became a more or less centralised crypto, but Vitalik was in charge all the time, no secrets there.
Eth still has more money, and the dev team. Etc stated to copy all the code from eth in the future, this will not make this the winning chain Imo.
(I don't own Eth or Etc, I don't believe it can work. I think blockchain/ sidechains is something for the core devs to make secure and not for everyone who wants to give it a go. Look at the DAO. But still I think Eth will be pumped and maybe become a valuable centralised crypto)
