It seems that Miners (in league with declared hashfollowing exchanges) can indeed dictate what chain is Bitcoin and identified as BTC on the exchanges. If the miners hang together when i say "Hey Google - what is the price of Bitcoin" I'm going to hear what the price of Bitcoin-from-segwit2x is at that moment, regardless of the intelligence, blood, sweat and tears that Core has put into Bitcoin.
Yeah.... but who cares about the name
When I first heard about Bitcoin, I got interested in how it was designed. How the name was chosen, or what the name is, is totally irrelevant.
It seems that all the arguments to fork Bitcoin away to this programming team or that programming team share this feature in common; they're all semantic arguments about the meaning of words.
Newsflash: the meaning of words is subjective. The math and design logic behind Bitcoin are not. And they're what make it powerful, not the name, lol
