But really, if S2X emerges the victor, is that really a 'worst case' for you Core acolytes? Seems to me that there ain't more than a RCH difference between S1X and S2X. Sure, a handful of overly-entitled neckbeards either whiny-ragequit or have their bluffs exposed. Other than that, what?
You are missing the point. If a bunch of people can meet and redefine what Bitcoin is, then that's the major problem right there - because at that point it has been proven that Bitcoin can be controlled or co-opted.
Why would anyone need a coin which is controlled by a group of guys who meet behind closed doors and take decisions for its future? We have FED and ECB currency for this.
Bitcoin has big inertia in order to change its rules, and that is ok because the alternative goes against the decentralization which Bitcoin stands for.
