What other high profile companies are putting hardware into the heads of chimpanzees? I am not aware of any. And even if it was politically motivated to investigate, the evidence would have to be made public and Musk would have had a day in court to challenge any enforcement actions. Surely the inconvenience to Musk’s legal team and the court system is worth determining if potential charges had merit rather than Musk deciding?
