I'm not a huge fan of Elon Musk, however ...
Giles Coren - who also called a "respected political journalist" a paedo on Twitter - writes in the Sunday Times today Whether we like it or not, words are cheap and becoming cheaper. Twitter is a dull, brutish arena to throw them around in and I think we should be free to say whatever we like there. I reaped the online whirlwind for my “pedo guy” moment but I will repeat it like a shot if he comes for me again. That said, don’t think for a minute that if some future billionaire calls me a paedo, I won’t go after him for every penny I can get.
I think what Coren is suggesting is that when someone is very wealthy, they are more likely to face a lawsuit, whereas someone like him who tweeted exactly the same insult, gets away with it.
Also, Musk tweeted that in response to he diver saying "he can stick his submarine where it hurts".
It's playground stuff (like we sometimes get on Gransnet, only worse) so it probably should not have made it to court.
I'll hide now.
