The reason they don’t want employees to use these words (and why they go OTR occasionally) is, at least as alleged by the government, to make discovery more difficult/impossible and also to hide/destroy evidence of their activity. It’s not about being word police, it’s about the reason why they’re policing language.
Do you not understand the basic principle of law that intention actually does matter? Or do you not understand that it may be difficult to prove that there was intention to commit a bad act even if it is trivial to establish that the bad act was made?
That's not a joke or something to take for granted. A lot of people in tech want law to be like a formal mathematics, and sort of pretend that's how it works, rather than acknowledge that fuzzy human things like "intention" are valid factors in legal matters.
