FYI, Elon, you can’t sue for libel/slander if what people are saying is actually true.
You can. You can sue for any reason that you can dream up. True, a lot of those suits would get thrown out on a motion for summary judgement, but a libel suit would likely pass the test of a prima facie valid case, and the case would proceed. Now, if the facts don’t support it, then you’d lose, but if you have a lot more money than the defendant, you can use procedure to bury them financially.
It’s one of the major flaws in the U.S. legal system, and anti-SLAPP laws are far too weak, since they usually rely on the defendant to try to enforce them.
Look at what happened with ABC News, recently.
