If I'm wrong then please link to a statement from Google that supports another reason.
I am not convinced any statement from Google is relevant in this discussion. Google releases statement based on their own self interest, like any big corporation. As webmasters, we need to look at what is actually going on, not what has been spoon fed to us.
