"managed to randomly announce" is a very odd way of saying "the CEO committed securities fraud because bankruptcy was imminent and his entire net worth was sunk into the company".
Tesla did nothing of the sort. Elon got into trouble for influencing the Tesla share price. Which is almost comical to think about due to how common it is to do exactly that.
Elon made a mistake of giving a specific number. If he just made any run of the mill bullshit grandiose claims it would have been fine. I really have no idea why people are so caught up on this. There is massive securities fraud actually happening every day, and people are hung up on some Twitter banter from half a decade ago.
FWIW, I have no idea, I just know that Tesla's inability to keep a legally-sound lid on Elon Musk has been a recurring topic for Matt Levine for years. He got in trouble with the SEC for the take-private stuff.
