Communication is a 2-way street. By definition you can’t blame it on one person.

Even if communication works two ways, sometimes you can blame it on a single person. Shitty drawing time:

I'm representing the people as houses, and the bits of info as vehicles. "A" sent "B" a problematic bit (the orange car), and everything stopped - because once those cars/bits of info won't be able to circulate further between "A" and "B", even if "B" did nothing wrong.

...that said I agree with the core of your text, I think that it's reasonable.
