There are a few references online if you search for '"american inventors" "google"' or something. For obvious reasons it was never covered in any tech blog.
How many references to e.g. Edison will you find online, remarking that he was "white"? In a context of ethnic debate in the US, mentioning "white" anything, will most likely revolve around "black" anything.
Got a reference on the Google incident? Sounds like misinformation.
