Hi, Howard,
You may not intend to be confrontational and accusatory and I certainly understand how easy it is to come across that way when writing as opposed to speaking without meaning to do so, but instead of asking why no one else is doing anything to improve this profile, perhaps you could add some sources to his profile, create profiles for his parents, and then PM the profile manager to ask that they be connected.
You don't have to do that, of course, but if you are unwilling, then you shouldn't expect others to be more willing.
