Because your comment is nonsensical.
First of all, they claim no position in the stock. Even if you don't believe it, they did research on a company, decided the business looks bad. Do you expect them to be long the stock? Do you think they randomly chose this company to "bring down"?
Where are all the people upset about situations where banks like Morgan Stanley, who have Tesla for a client and own huge portions of ARKK (which in turn owns many Tesla shares) put out ridiculous reports claiming Tesla Insurance is more valuable than Geico, Tesla "parts" is bigger than VW and Tesla autonomy is worth billions, in order to juice the stock upward?
The bias is unbelievable.
(Disclosure: I hold puts.)
Your claim that they have a position in this case was incorrect, because you can't be bothered to read what you're commenting on, and that's probably why you're downvoted.
