There's a $10+ billion short position against TSLA, constituting over 25% of outstanding shares. Anyone working at Tesla should be paranoid. Remember Enron? People invested deeply in something do criminally reprehensible things.

Much more importantly, Musk made very concrete allegations, the truth of which should come to light in short order. I remember the insinuation SpaceX made during the 2016 incident, which was much more circumspect. If this allegation proves false I don't think people will be as forgetful about the attempt at blame shifting.
