You need to be able to use these models for the real world and not for some imaginary world where everything is safe and nice and happy all the time, while at the same time intensely surveilled in the name of CYA and the latest panic about whether speech THAT ISN'T EVEN BETWEEN TWO PARTIES is considered "wrong".
I'm a free speech fan that acknowledges there are lots of boundaries of free speech (fraud, perjury, blackmail, defamation), but the one thing that all of the boundaries have in common is that a second party must be involved for them to make any sense at all.
Maybe the courts will uphold this, maybe they won't, but don't take the risk!
