I'm not technically astute enough to weigh the details but the whole creation of ETC effectively as an accidental side effect of the DAO hack, just smells very bad. I totally agree that the prime issue is non-technical...the community is fractured and consensus is a human problem not a technical one (just like the bitcoin block size issue). The crypto-currency and blockchain worlds are complicated enough the DAO hack and the resulting ETC creation are not good things. Of course the whole issue of the immutability of the chain is a real issue and I suspect is the philosophy behind sticking with the old-chain (classic). It's certainly a mess and I tend to think that ETC should just go away.
