Wow. I knew Stephen Pair and Bitpay were scummy, but I actually expected backtracking from them, given how outspoken Core developers have been against the November hard fork attempt. It seems like they're really setting the stage for a split of the network.
I won't lie. Even if it were just Bitmain and Bitpay alone fully backing a fork, I'd be worried about how bad the split in userbase and economic activity could be. It looks like there could be significantly more support for the 2x fork at this point than just them, too.
I worry that Bitcoin Cash was used as a test bed to show that a "Bitcoin hard fork" can't succeed without majority hash power. This implies (fallaciously) to many that it was hash power that explains the failure of Bitcoin Cash. Enter Segwit2x....
