It could have been posted May 20, 2024 and I don't think it would have any real meaning. Musk has zero credibility with this sort of thing regardless of when it was posted.
You try telling Elon Musk not to post stuff. He ended up being forced to buy Twitter and pay an SEC fine because he tweets too much. He's going to post whatever he feels like, no matter what you, or anyone at Tesla, or the SEC says.
I wouldn't be surprised if Elon considers it just. Most people consider it just that a revolutionary technology owner is being held liable for their actions, even if they are nearly a decade afterwards.
Regulation for big corporations are more like suggestions these days, so this may even feel "fair enough" for Elon in retrospect.
Or the tweet was bullshit, and Tesla will do what every company does and determine whether it is better to settle or not based on the financial cost/benefit and not the truth or validity of the claim.
