No it's simply a long play by    Google today Microsoft almost  has a monopoly in the workplace because of Microsoft office and windows and how people are used to it when they join the workforce.
   Later as more people join the workforce having used Google app more corporations will be will to move to it as the cost of retraining will be less.
  If Google let's students use Google apps without mining their data today they can mine it later when they are not students and join the workforce as adults. And anyway they are selling Google services to recover the costs.
