Closed co-op?

Tell me if I’m wrong about Google Co-op — because it’s damned near impossible to tell what it is from their description — but it seems to be a closed system for enriching Google but not the internet. That is, it gets us to give Google meta data about sites that are supposed to improve their searches but, so far as I can tell, that data is not available to anyone else. Closed? Evil? You tell me.
