Speculation: Perhaps they use GAE, or another of Google's services as part of their stack. Or they use Google search heavily for looking up references.

Thank you for the downvotes, I appreciate it. Now would someone mind explaining how you can be dependent on Google for your job?

Probably not what OP meant, but I usually have to look something up on Google for every few lines of code I write.

It takes me less time to look things up than to learn em properly.

Okay well that kind of makes sense thanks. I use google all the time for gmail, analytics, admob, google searches, etc, but there are alternatives to all of it.
