I am 100% in favor of the destruction, de-construction, or outright implosion of all centrally controlled for-profit walled-garden[1] social media sites, and none more so than Twitter. The primary harm such sites promulgate is a positive feedback loop of extremism, fostered in the corporate chase of engagement, solely in the name of profits, while the social discord they engender, now veering sharply toward political violence, is foisted on the rest of us as an unpriced externality.
