I don't think the thing driving this initiative is public sentiment. The public, obviously hates child abuse and that's a convincing argument. Child protection organisations might be vocal proponents... but law enforcement, mi5 and whatnot are also probably strong advocates and tend to have the ear of governments. This is a security/law enforcement issue.
