Coinbase, BitStamp, and Blockchain.info upgrade. These nodes provide a lot of the infrastructure for Bitcoin, so if they do not upgrade, Bitcoin New will be a lot less useful. However, these nodes are in it for profit, so they will tend to go where the money is. They cannot necessarily afford to wield the influence they might have at the risk of short-term losses.
He's totally wrong about that. All three of those are startup companies that exist and are funded in order to achieve a large future payoff, generally at the explicit cost of short term losses. They will do what they feel provides the best long term payoff. Avoiding short term losses is relatively to entirely unimportant to them.
That still may not be the choice of fork that he or you or I would prefer however.
