So, basically... "an investigation into whether we lied to customers in order to sell them stuff would have an impact on our business". Well, yeah, that's true. Shockingly, customers don't like being lied to about the quality of the goods they're buying, and hearing that there's enough indication of lying to warrant a full probe into it would make future customers hesitant to buy. While wrongdoing hasn't been proven yet, I can't imagine this probe would be happening "just in case" Tesla lied - there must have been a high volume of complaints from customers who aren't happy. The precedent set by not investigating would be awful. It'd basically say businesses can claim whatever they like about their products, because being caught lying about them would always have the consequence of "material adverse impact on our business".
