Short Seller here
I will answer this question honestly.
I am pro green energy and pro EVs in general and I definitely cross the line from shorting Tesla to outright hating them.
Tesla is a dishonest company that is doing far more harm to our environment than good. Mining lithium and cobalt is not good for our environment in the quantities currently required for battery technology (PHEV far better for our environment, but they arent as fast!). Neither is selling huge butane lighters and calling them flamethrowers or ~creating super enormous batteries to make your cars extra fast!
The entire concept of 'helping the planet' is farce, and Tesla does not affect the adoption of EVs any nominal amount. Im sure you think they do but they don't. The price/quality of batteries and the affordability of EVs will dictate mass adoption, nothing else. If you think tesla is good at mass producing cars for cheap, well....lol.
All of that is not why I hate Tesla though, I hate Tesla because they lie. I hate them because the only goal they have is to pump stock price and enrich themselves (really Musk and his cronies), all the while sucking up government funding that could go to actually helping the environment. I mean literally we are subsidizing cars for people that can afford 100k cars. That money could be spent in so many better ways if it is truly meant to help the environment. Right now taxpayers are funding the lifestyle of elon musk and the toys for the rich, if you think anything else you are either not intelligent or willfully uninformed.
Combine that with phony timelines and promising things that they know are not possible, resulting in killing people who they then blame for not using the product according to the legal terms (even though they call it auto pilot). All of that really bothers me because I hate lying and deception. If you don't see it, it's because you just dont want to.
This is why i want Tesla, but more specifically, Musk, to fail. The sad part is no matter what im pretty sure he walks away from this hyper rich and many people, including many on this site, will walk away with a significant hole in their finances.
