Good point. I have never considered this argument before, but I agree. In a healthy case, the sphere of responsibility (of a company, individual) should approximately match their sphere influence. And with a sphere of influence this large, this goes far beyond the "contract" between individual parties only.

In some cases this kind of relationship auto-regulates itself (e.g., taking a small vs large credit in a bank): at larger scale, both parties are invested into maintaining a good relationship. The problem in this case is, any individual investment into any relationship with Google is just a drop in the ocean.
