Nodes are the validators, miners moving off the network only have the power to temporarily adjust the block time. If we keep our nodes on the network with true innovation and development of applied cryptography (MAST, SegWit, bridged payment channels, tumblebit, schnorr, etc) then the miner fluctuation is merely a temporary nuisance. Undoubtedly some will realize that it's dumb to run a client controlled by people and developers who are amateur at best, have nothing to contribute aside from porting code from core devs, and has an openly admitted purpose of "political compromise."
This is a problem of "industry leaders" thinking too fondly of their own importance. Bitcoin will continue to force their humbleness or ignore them. They simply cannot make the decision they think they have made for us. Being their important selves, they have "solved" our scaling problem and only need the political power and influence to make sure this is easy to do again in the future. That arrogance, desire to control, and political nonsense is the very thing bitcoin is designed to resist.
I've got a full node, and it's staying this time because I didn't fully appreciate how critical it was to keep one running. The NYA "agreement" by a few companies who think they speak for me has made me realize. So I'm not running 2X hardfork on my node. Regardless of whether the entire network splits and does something else. I'm following the developers who know their shit and are actually killing it with new cryptographic applications and brilliant security, thorough testing and implementation, and breakthrough innovations. And I can run that network all by myself if I have to.
Join me. Start up a node. 0.15 is much faster at initial sync and operation. Stake a claim with who you want your developers to be.
TL;DR I didn't sign the NYA. They don't have the authority to speak on my behalf. My node will never run 2X and that's all that matters.
