The point isn't necessarily what has come to pass yet, it's the focus on things that don't necessarily have a path to revenue yet. Everything Apple does is product and revenue focused. That is not the case with Google.
You are right that 95% of their revenue comes from Adwords . . . but 95% of their efforts aren't on optimizing Adwords, and that right there is my point: Apple is focused on executing where their revenue is, Google is definitely MORE focused on finding new revenue opportunities, and is more willing to look into unorthodox industries and ideas.
