Responsibility in communication is a two-way street, and also depends on incentives and relative power.

- Are security researchers grossly incompetent for failing to convince the IT industry to adopt best practices?

- Are voters in democracies grossly incompetent for failing to police their politicians and keep them honest?

- Are media outlets grossly incompetent for not squeezing out 'fake news', whatever your definition?

- Are epidemiologists and public health officials grossly incompetent for not convincing anti-vaxxers of their foolishness?

Anytime there is a breakdown in communications, both the listener and the speaker should probably shoulder some of it.
