Why did these YouTubers give away their son?

Why not use a title closer to the article in question?

"Un-Adopted : Influencers shared every step of their parenting journey, except last".

The article is a tragic story of a family that adopted a special needs child from out of country and the hidden nightmare of being (despite their best intentions) unprepared/unable to deal with the results. Fortunately for the child in question, they have now been placed with a family that has a parent with the proper medical training and I am assuming no other children. The other thing in play here is our society's perverse desire to produce and consume "reality porn".
