Yes.Im a bit lost in this and admit have only caught the head lines. Elon is throwing a tantrum, because private companies don't want to do business with his private company?, and he's saying " No, you must pay me and always do business with me?"
Apparently for Musk "Free Speech" means you must advertise with him, and anyone who says otherwise, or does anything to discourage it is doing something illegal.
The funniest part of the lolsuit threat is that he's apparently going to try and go after people who just donated to the organisations that were pointing out the type of content that adverts are currently running alongside on Twitter.
I guess the richest man in the world must have a hobby to entertain himself, and when he's not trolling on twitter nothing quite wastes money like frivolous lawsuits* involving your very expensive lawyers when the matter will get thrown out of court on long established precedent what anyone who has passed law school will know about, and that there will likely be a line of lawyers willing to work for free to defend.
*Well I can think of one or two things, but apart from spaffing 20 billion or so on a joke, lolsuits are pretty much the top of the list.
