Agreed, I'm not sure how any of this disagrees with:

"It is an explanation. The article does not propose an alternative to the imbalance explanation rather alternative focus of action to achieve said intake balance."

I understand the article wishes to point out we should focus on a different action but it spends its time attacking the current definition not because it has a problem with the definition but because it has a problem with the currently popular action associated with the definition.

The popular definition is fine, it's the popular "soluttion" to the definition they attack. The paper is much more clear on this.
