The way I look at it now, the Borg (Google) wants to grab CSS and JS so that it can keep users on its advertising portal. The snippets thing is just an attempt to make their advertising portal sticky. Good search engines give people what they want and should have a high bounce rate. But then I'm cynical and I'm not a Google fanboy.
