>What you're describing is not being caused by free speech, it is being caused by online media filter bubbles that feed people confirmation bias, elevate controversy over quality, and isolate users from opposing opinions.

But free speech must allow for filter bubbles and confirmation bias, and elevating controversy over quality. Free speech must permit manipulation and distortion, indoctrination and radicalization.

>Traditional media used editorial discretion to solve this problem, but SV seems to think they can make more money by skipping that step entirely.

SV was exercising editorial discretion by moderating content and banning troublemakers, but free speech supporters have decided doing so violated their free rights. You can't have your cake and eat it, too. "Editorial discretion" by definition is a mean of forcing people into silence, which you're against. You want the crazies to be able to express themselves, so the modern social media landscape is what you want, because that's exactly what it optimizes for.
