That's not really how things work. Not only is that sanctionable but extremely unethical and would result in diciplinary action if reported.

How would they prove that this "threat" took place unless they recorded every conversation?

The fact is that this extreme example is just an example. Lots of companies just send a bunch of intimidating letters to people and hope it sticks - because it's free!

I'm sorry but defending the ethics of lawyers outside of a majority legal environment is a losing move.
