2021 Prerefresh Model S
OK, I now understand the issue here, does the car have a HomePlug PLC modem or something similar? I was lumping that together with the J1772 signalling which isn't correct for SAE CCS.
However, this video with a Tesla engineer who worked on the Tesla plug design and was also active with the SAE standards group (to his ultimate disgust) also claims that Tesla is compatible, specifically both electrically and signalling, but obviously not mechanically. It's certainly possible that both he and Straubel were misspeaking, but the questions are pretty specifically about DC fast charging, and as engineers, they'd have a very clear idea of what the issues were.
The SAE Combo discussion starts at about 1:45.
