I wouldn't assume that Google's search results reflect anything but an attempt to bring you back by showing you results you find valuable, and to monetize your visit.
> scrubbing it to better reflect a chosen set of cultural sensitivities?
Google (and any other mass market vendor) removes a lot of things that people don't want to see, including scams, X-rated content, brutality, etc. People searching for information on their dog don't want to see bestiality. These aren't arbitrarily chosen preferences or mere "sensitivities", but social norms which in many cases have a strong moral foundation.
Conversely--haven't these same people been telling us for years that we live in a racist society? So why are they surprised that a search engine of a racist society's web pages returns racist results?
> why are they surprised
Nobody said they are surprised; that's not relevant. They are trying to solve a problem, just like people who are working to resolve the problems of cancer, gun violence, and bugs in Firefox.
Examples of how the author is approaching the topic more generally are found in headings such as "Content and Creators" and phrases like "Information monopolies such as Google".

I agree that results in Bing and Duck Duck Go, for example, currently show a lot of the flaws describe in the article. But the point (as much as the headline may lead you to believe) isn't that it's only Google.
rayiner was saying that there is a "coupled system" and Google just reflects external racism, and then Google's search results amplify racism. The article did not mention anything about those interesting points, which might be worthy of bringing up and discussing, but it seems very unfair to accuse the top comment of "not getting the point" about them, when they are rayiner's insights that were only now presented.
(Google does this with everything else as well. What do people think of the new MacBook Pro? Searching for reviews will immediately spit back a concentrated and distilled version the first mover opinions, which will itself drive peoples’ opinions.)
