Yes but most of the other children don't have vocal middle class parents and are already part of the social care system and no-one really gives a stuff then. They were already unwanted by the people that should have cared. Why this family have not been challenged for child abuse I really don't know. yes, it was unfortunate what happened but if you leave children of that age and you live on a council estate you have social services take a real good look at your ability to be a parent.
actually i think that is more the reason the media ran with it. They can be "oh save the children poor maddie" in the articiles but that would get boring fast and not get sales the fact that there is a conflict of "poor parents having their child stolen" and "evil/neglectful parents killing or losing their child through negligence" means there will always be debate, it will always be a talking point and people will want to read/hear about it gaining views and sales.
