I agree with your point about human level communication and treating the recipients like they matter. I generally tend to prefer communication that is more on the blunt/direct side, but if there's one thing about communication that I've learned throughout my career, it is that the people who do best are adept at communicating well with a wide variety of people with different communication styles and preferences.

The people who try to force everyone else to fit into a specific bucket of communication style, or who refuse to deviate from their own strict communication preferences no matter the audience, those are the people I see struggle to find success relative to their peers.
