You could have a bunch of OOPs-fanatics who will hate the functional programmer who does things differently. Toxic culture (lack of self-awareness means that 99% of people don't know they are participating/creating/perpetuating the toxicity) means this functional programmer is demoralizing the team.
That's how objective IT is. Its culture wars of this sort - misplaced fanatic sincerity and close-mindedness, or worse mean-ness. And its demoralizing to the majority. Hence the PIP. Its like a dystopian landscape.
