A bit off topic from the original proposed edit maybe, but out of curiosity I ran the query:
nwr[source~"google",i];
(._;>;);
out meta;
and got 60MB worth of result and ~40k objects. all listing google in some form in the source tag. Thats quite a few objects. It might also be an idea to sort those out sometime. No clue how to best deal with that, since copyright is involved.
This included sources such as:
source=Google Streetview June 2015 image
source=https://drive.google.com/file/RestOfTheUrlRedacted
source=Google Workspace Updates: New community features for Google Chat and an update on Currents (lol)
(sidenote: also found over 500 dead google+ website links)
source=Google
source=Google maps and local knowledge
source=Bing and Google
source=Google Sattelite
