"synergistic leadership" or "growth-hacking paradigms" are, in my opinion, what my teenage son refers to as "brain rot". I don't know where these people come from who make up these terms, or what childhood trauma has done this to them, but I absolutely cannot tolerate any of it, it makes my skin crawl.
It's a bit better: They are forms of obfuscation and lowering information in a channel. They are designed for environments where being clear is very risky. In certain organizations, you are better off being unclear than asking for approval or consensus on a tricky decision: You produce an incomprehensible, vague mess of a message, and avoid argument, as argument in those places leads to paralysis.
Now, does this mean it's the right way to talk everywhere? Of course not. And since it's often seen as safe, it's overused. But it doesn't just arise, as a bug. plain language that means what it says creates more conflict, and isn't always better.
