Earlier quoted context omitted.
Short sellers have been causing the company a lot of trouble, Musk is correct in pointing them out so that their activities become known.
No, they really haven't. The best way to deal with shorts is to have a good quarter and crush them all. Or wait for a short squeeze. Lots of companies have misinformation spread by shorts all the time, but very few companies engage and attack shorts.
I'm surprised any company has the time to engage and attack those kinds of threats, but I'm not surprised there is an incentive for them to do so. Is it just the lack of time (or maybe optics, for whatever reason) that other companies don't "fight back"?
