1. Elon and his brother hold most of the stock. He does not need to be the CEO to control Tesla and profit directly.
2. Tesla are garbage cars that keep getting people killed and injured, even getting trapped and burnt to death inside.
3. Tesla commits odometer fraud to avoid honoring warranties they sold to their customers.
4. Other automakers who have been building cars for decades longer than Tesla have superior electric vehicle offerings, and much cheaper prices.
5. Tesla committed rebate fraud in Canada.
6. Teslas are one of the most expensive vehicles to insure, because they break down and malfunction at higher rates than other comparable vehicles.

I could go on and on and on, but the above alone should be sufficient.
