First, how are these clickbait titles, when it is all documented? Second, did you not see the last link with a quote?
https://family-law.freeadvice.com/family-law/child_support/Child-Support-for-a-Child-That-Is-Not-Mine.htm (child by consent section)
"Laws favor someone being named the father because they do not want a child going through life fatherless. The equitable doctrine of estoppel applies to persons who have for all practical purposes consented to being dad, regardless of paternity. The basic theory is that since you acted like a parent and permitted the child to believe you were their father, the child now has a right to rely on your representation that you are their father. "
It's clickbait because of the titles and the intentional lack of information detailing why they got stuck with Child Support.
And you can quote that all you want, but that law is only going to be applied to children with no father on the birth certificate when you were married the mother. So again: stick with stuff you actually know.
