Am I in the minority thinking that “complexity is the cause of failure” may in fact be a useful and actionable statement? Start analyzing where complexity resides, cope with failures caused by inevitable complexity…
Of course, qualifying the sources of unnecessary complexity would be even more helpful, but even merely pointing it out may be more strategically useful than “X and Y caused an error”. (So you’ll fix X and Y; then Z will start causing trouble.)
It’s a tangent, I agree that “culture is broken” does seem like a useless statement.
