I can see how [the diver personally insulting Musk's efforts to try to help the cave situation] would tee off Musk to the point where he responds on Twitter. It'd certainly piss me off, and I'm not a billionaire who's put my all, both financially and personally, into the Tesla mission over the course of more than a decade, all the while dealing with endless negativity from all corners, much of it presented in bad faith. That he eventually snapped is understandable. Perhaps it was inevitable.
The problem is that Musk then responded with the indefensible: calling the guy a pedophile. That's a serious allegation and one that even if he has evidence for, should be made to the proper authorities and not to the public via Twitter. If he doesn't have evidence, it's clear libel and given the relative net worth and popularity involved will certainly involve significant sums of cash being transferred from Musk to the diver.
I'm glad Elon deleted the tweets, as it shows that at least he realized he made a mistake. Hopefully he realized this on his own, and he knows he actually screwed up rather than having just reacted to the negative press.
