Google Fiber is taking over and people will choose it over their regular ISPs because it's better. And soon enough it won't matter what OS your mobile device is running. For as long as you're connecting via Google Fiber, Google has your data.
I solved this problem with a VPN, just like you need with AT&T or Comcast.
