For example if Facebook could have better communicated the nuance dangers of getting addicted to Instagram the world would have been a safer place for teens.
Lack of nuance often serves a purpose. For example, Facebook doesn't necessarily have any interest in making the world a safer place for teens. Corporations in the US do not necessarily serve the public interest as understood by people who aren't the corporation's investors. Instead, the rule is profit uber alles, though Milton Friedman wasn't quite crass enough to phrase it in so blunt a fashion.
Also, I don't trust "nuance" in corporate communications. I'd rather have plain English, stripped of all euphemisms and doublespeak. Of course, that probably wouldn't be profitable and sound too much like Lily Tomlin on Caturday Night Live:
> We don't care. We don't have to. We're the Social Networking Company.
