What it boils down to: post civilly and substantively or not at all. Put differently: if you have a substantive point to make, make it thoughtfully; if you don't, please don't comment until you do.
I realize that it's hard to separate a tone that makes the mdoerators unhappy and content that makes the moderators unhappy (I didn't read the comment above as unsubstantive or uncivil at all!) but you gotta play by their rules.
(Or, I guess, burn HN down and start a new one that isn't subservient to capital. I'll join.)
In the meantime, HN is merely one specific kind of community, and it has specific rules which, if people want to participate, they have to follow. Those rules are at https://news.ycombinator.com/newsguidelines.html. They're not hard to follow for anyone who wants to.
Ok, so we burn the system to the ground. Then what? Crown bitJericho king?
It's such a silly mindset. Do what we currently do in US or anarchy. There are over hundred other countries on earth and significant fraction of them is doing way better than USA in most aspects.
Adopting something more akin to European style democracy (which is what I assume you're mostly referring to) is already possible within the US system. That it hasn't been done yet isn't evidence of corruption within that system, but of the culture of the US simply not wanting it.
You need really a lot of disregard of previous system and power to make any significant changes. You'd need either revolution or invasion. Obama inaptitude shows that the system can't be touched from within even by smart person in position of highest legal power.
