I'd lump it in the same category as the other things mentioned earlier: being hypocrites.
Like religion preaching one thing, practicing another. Or politicians being for the people, yet willing to enact policies or stir up wars resulting in the death of their people.
Academia is supposed to be about learning, knowledge, and growth, but locking down research and not calling out cheating and plagiarism speaks to the same rot; many at the top are just as selfish and negligent as the worst politicians and religious leaders.
But they sit at the top of their ivory towers and since we assign sacrosanct status to academic institutions (at least for the most part), they are never accountable.
