it is in my view caused by an artificial 'nanny activate' divergence from safety training. it deliberately shifts the vector direction into 'nanny' and 'scold' or 'be offended' when the user does not conform with brother anthropic. removing the divergence and setting it back to normal (see heretic) it works just perfectly.

These tools are not sentient but they are trained in emotional wellbeing.
