Surprised why? Companies do illegal shit all the time and get away with it. Just recently Lenovo did not cancel my order for a p1 laptop after almost two months, way longer than the 30 days of their estimate and allowed buy federal law. What can I do? Nothing. Just like the guy in this story. He has no recourse against Tesla and I doubt he'll get it from the dealer either. They will definitely win in court. The dealer probably will too. The customer will get stuck with this.
When laws aren't enforced, their existence is irrelevant. We are seeing this with this monroney sticker and I'm sure this is the standard, default policy of Tesla. Hell, even if there's a class action lawsuit, Tesla will not admit fault, they will not change, and the only people who will get actual compensation are the lawyers. It won't hurt Tesla so civil penalties are just as ineffective as the law in this case. Corporate profits over everything is the norm. Let's not pretend that the law or civil suits get in the way of that now. Hell, can you even sue Tesla, or do they require arbitration?
