Not this nonsense again.

Larry Page: "we want to get you out of Google and to the right place as fast as possible"

That was pre-IPO Google! if you haven't noticed the web changed quite a bit since then and companies do evolve, especially the ones who want to remain relevant.

Also It's not like Google is selling the items in shopping search it's just a different view for shopping results, and I'd argue that sending users elsewhere and not computing the solutions (results) or visualizing them immediately is a weakness that I'm glad to hear Google is working to address.
