Of course, while the paper is published by "independent" source, Google has commissioned it for less than honest purposes:
Google commissioned the paper, presumably to help ward off calls for government regulation of its search results.
As noted previously, Google has come under TONS of scrutiny from different governments and several U.S. government agencies. They have used their monopoly to illegally promote their own other services, all hidden behind the old "but it is just our algorithms at works!".
As Google is maintaining strict editorial process of the search queries, I think it would be good to hold them to responsibilities for them too. Google has shown that they can remove content from their service. Just like newspapers aren't allowed to show illegal things, Google should not be either. If Google has a problem with this, they need to stop manually deciding what's good for people and use an algorithm that is actually fair and isn't biased.
