Tesla switched to the CCS communication protocol due to European requirements. Newer Teslas sold in the US speak CCS but use the NACS connector. Older Teslas need a hardware upgrade to use newer Tesla superchargers. CCS cars, even with an adapter, cannot use older Tesla superchargers as those don't use CCS protocols.

I don’t see how the adapter would work without a GM agreement with Tesla to translate the data to GMs CCS fast charging protocol. Similarly I bought a few years ago a ChadeMo adapter ($400 from Tesla) that never worked well due to the incompatible data transfer to Electrify America fast chargers. The few times I tried it, I had to call Electrify America 800 number and have the technician remotely close the HV charge contactor to initiate charging.
