There's still zero evidence that any of Musk's claims are true, and I believe a few of them have always been trivially falsifiable, eg, Musk mentioned a child bride, but the diver's partner is 40, which isn't really what I'd consider a "child". And so on.
The court cases are ongoing, and unlikely to move fast. But at this point the best Musk can hope for is a procedural win I think, and that's iffy.
I believe his lawyers were recently advancing the argument that the First Amendment lets you lie about people on twitter, so it doesn't matter if all the twitter claims were lies. If that argument works, that would be a procedural win, aka "it doesn't matter if I did it, because X".
Musk is trying to get the case dismissed as being just a big joke, after he repeatedly challenged Unsworth to sue him.
Musk really screwed the pooch on that one.
...it still won't be the most expensive time he ran his mouth on twitter, said false things, and had to pay a big settlement that year.
(Musk had to pay a $20m fine to the SEC for making fraudulent statements on Twitter. Musk is on record that the fine was "worth it". And I guess if you're billions, maybe a really satisfactory tweet really is worth a few million.)
The US has a law (SPEECH 2010) that means English libel cases can't be enforced in the US unless they meet US law.
That would be fun. Extradite Musk. Classic.
Not sure if the case could be filed in Thailand. But if it was, Musk would be convicted for sure. The rescuers are all heroes in Thailand and what Musk said was very offensive and designed to do nothing other than defame the rescuer. Nothing would come of a conviction as long as Musk never visited Thailand again since nowhere would extradite him.
