I mostly agree. But if the communication tool's owner knows or ought to know of the death threats, then perhaps they should bear some liability.
(If I were the communication tool, I'd add some term to my TOS that the user indemnifies me against losses due to speech the user made. So if I get sued because of something you said, I can come after you for the losses. Of course, this requires that you KYC . . . so anonymity might become harder in a post-S230 world. I sure wouldn't want to be someone running e.g. an anonymous far right or militia forum if I could be held liable for wrongful death or harassment claims.)
