Since they took it upon themselves to curate the content on their servers, and in the EULA claim they can use that content as they like, it is THEIR content: they own it, they publish it to the public. Sue them for the death threats, libel, slander, and whatever else. It happens to other information outlets, why not them?
Not a free-market solution at all, I admit, but there is NO way they can curate content and then say it’s not theirs. The time for them to have it both ways needs to go.
Not a free-market solution at all
Sure it is - "free market" does not imply the right to make death threats.
