What's with Google services?

I noticed recent surge of new scripts running through the game. Scripts come from sites google-analytics.com, googleadservices.com and googletagmanager.com. I'm curious why is it ever needed to incorporate google services into this game? Surely BB wont run ads here? I was under the impression the game is profitable on its own.

web bugs, nasty little things but easily blocked if you run Firefox, just get the wonderful add-on named "Ghostery".

Could this be a reason why the game is responding slowly since a day or two?
