It doesn't seem obvious to me. It seems like one of a few interpretations, not limited to:

- Elon was overly stressed (as has been documented recently) and didn't think before posting such an impactful statement

- He considers twitter to be an official outlet for Tesla and just continued with his tendency to publicise his decisions and thought process constantly.

- His idea of "secured" is simply different from the SEC definition and if the funding had been SEC-secured, the tweet would be a compliant form of public disclosure.

[edit]

To be clear, I'm not arguing that the tweet shouldn't be investigated. I'm saying that "he intentionally lied to screw over short sellers" is presumptive and that may not have been his intent.
