As I see it, it's a case of ignorance. Tesla drivers see the "TESLA" logo on Tesla Destination Chargers, and they think that those chargers belong to them exclusively, like Tesla Superchargers. What is needed at Tesla Destination Chargers is clear signage, which identifies the business where the Destination Charger is installed -- and not Tesla -- as the owner of the charger; a sign which states that the business/ property manager sets the rules for who can or can't use the charger. If Tesla wanted to block non-Tesla cars from using Tesla Destination Chargers, they could do so with software. They don't, which to me suggests that Tesla wants all plug-in EVs to be able to use their Destination Chargers. Just my opinion, but many agree on this.
