Just pointing out that the in-car navigation doesn't show reviews for superchargers when navigating to them. And that's what most owners use primarily. People don't usually choose chargers because of reviews, they choose them based on when they need to charge, like when travelling.
And that assumes that drivers even use the navigation and don't already know where their usual chargers are already.
That effort should be used elsewhere that is more effective. Reviewing chargers negatively is just going to waste time for something no one looks at, shouting into the void essentially.
