Never mind that in this case, I believe that Google was right — Richard Veryard correctly points out:

Look at BMW’s position from a service-oriented perspective. BMW’s promotional and marketing capability is critically dependent on Internet search services provided to BMW’s customers by Google and its competitors. This is of course true of many companies, large and small. But for most or all of these companies (and I presume this is the case for BMW), there is no formal contract with Google that governs this particular dependency, and no defined service level agreement.
