Google want to control the comments ?
Comments system adopted in blog systems long time ago. Now Google want to take it back to control. What's the fact is ? It's a big question mark of many webmasters. Even they would think that readers can spam their pages without control. From my point of view, google count on this factor when they design the system. They can filter the spam comments easily then other blogs. Why ? Because the comments are under control by them ! It is easy to figure out who is spammer and block it.
