>Of course consensus is, by definition, whatever the majority is doing. So now it's a battle of dev's trying to cajole enough hashpower into enforcing the rule, or somehow backing off the change. With every new block mined on each head, there's more money at stake for which way the decision ultimately falls. For Bitcoin to survive, "There Can Be Only One".

Consensus is what everyone is doing. That is why the terminology used here would be "split consensus". The purpose of the devs trying to get the hash power back into the correct blockchain is so consensus can be re-established.
