LOL! Ya got that right. But, why are you right?

From my experience teaching these topics for over a decade to thousands of pilots, I would offer the observation that those who have come to understand mixture management and routinely operate LOP are the same pilots who have gone to the trouble to become educated about the relationships between the EGT, CHT, ICP, HP and BSFC curves as well as the value of engine monitors and how to interpret the data they display.

I would also agree with your premise about builders placing blame. These are usually the same builders who've never operated an engine LOP or even looked at the 5 Landmarks to Engine Management, much less understand their relationships. If one cannot draw the EGT, CHT, ICP, HP and BSFC curves they have little chance of understanding the issues we are discussing so openly.
