Right, but why does Reddit care? Their moderation approach effectively addressed the business problem they faced. Maybe in the long term Voat will grow to become an existential threat to Reddit, and Gab to Twitter. But it sure doesn't look that way right now. A reasonable business manager at a firm like Reddit might look at a new company like Voat as a gift.

It doesn't seem like a reasonable organizational goal for any firm anywhere to eliminate white supremacy from the entire Internet. It's hard to imagine how that might be accomplished. Certainly, Reddit was never in a position to do it. Why would they look to solve any more than the part of the problem they were directly engaged with?
