> That's not the issue. Nor is his desire to hurt them. That's a huge issue. If he made his misstatements with the intent of hurting short sellers, that's criminal fraud. If he just made a material misstatement, with no intent to harm anyone, it's a civil case.
You inserted "intent". That is the key question, not whether he dislikes short sellers. Every CEO dislikes short sellers, and nearly every CEO makes "material misstatements" now and then. What separates that from fraud is what the SEC focused on in their comment: scienter.
Scienter just means intent. It's literally just the fancy legal term for intent.
Thus, it matters very much that Musk has a history of trashing short sellers and wishing harm to them, because they can use that history to establish that his tweet was made with the intent to defraud market participants and materially affect the price of Tesla's stock.
Especially the "funding secured" bit. You don't say "secured" if it's not really secured. There is no legal interpretation where "secured" is a harmless mistake.
