Edit to add from a below comment I made: I mean more in the scenario of a cell going bad, causing a fire, then maybe blowing up the car and causing collateral damage. As I understand it, this would be covered by the car's insurance, right? If so, Tesla shouldn't be locking the chargers (Maybe Tesla would need to verify insurance before allowing supercharging then). But if it doesn't, or if the car is uninsured, then I can accept Tesla not wanting to be held liable for the damage to their station or other owners' cars for batteries that might have undetectable damage.
