Or maybe, Google just wants to train people to work on their platforms rather than moving to a competitors. I doubt google has the intention of hiring the people that graduate from these programs, they just want people to learn google apis so that they use their products over competitors. This can be seen through how companies sponsor hackathons, the courses they create on websites like udacity and so on.
