The Design Studio shows Supercharger hardware included.
1. Elon misspoke.
2. There is optional Supercharger software.
3. Elon was referring to usage charges for the Supercharger network.
4. The Design Studio is wrong.
5. The article quoted Elon incorrectly.
Given how ragged Elon has been running lately, I'd suggest the most likely is #1 with a saver on #5. Charge and no-charge went back and forth for a long time and the Design Studio used to say TBD for the 60 kWh pack.
My money is on #3.
