No actually nodes are ran by many other normal users and bitcoin service providers along with the miners but miners play important role in hard forks. After hard fork the network which will have majority of mining power will survive while the one which doesn't have much support from miners will ultimately die.
Thanks for that... Could we see repeat of Ethereum? Both ETH and ETC are still alive 10 month after the fork with sufficient hash power to support each branch. Ethereum brand has survived so far... I guess ... Nah, we should be fine.
Yes, we could. Bitcoin Unlimited might get the miners, but they'll never get node consensus.
This will ultimately divide the Bitcoin community, the network that has the majority of mining power will prevail, but it will be ugly just like with Ethereum.

A hard fork is expected should either of the two reach ~80% miner consensus, but it's impossible at this point so it could be lower.
It's sad how only miners decide the future of Bitcoin.
well not really without exchange miners can't do much, they won't be able to sell their coins, there is always chinese exchange one could say, but i doubt they are in agreement with BU and will list it as a an altcoin anyway like other major exchange
the situation doesn't look that back 36% is not even half of what they need, and they still have only antpool supporting, i fairly certain this fork will not happen
