Why? How do you "abuse" Superchargers, by using them?
In 2018, Tesla was hurting for cash. They did many things to make sure the cars they could build were actually sold. One of those things was the free, unlimited Supercharging. A significant number of those cars sold with free, unlimited Supercharging were sold to people who had no way to charge them, other than Superchargers. Saying they were abusing the program is just plain silly. That was the intent of the program, to encourage purchases by people who otherwise would not have bought.
This is no different from the drop in price for the free, unlimited full self-driving. Am I abusing the system because I use it so often? Actually, I hate the full self-driving, never use it anymore. The autopilot is much more user-friendly. $2k wasted.
