     There are lots of Wi-Fi hotspots out there but not all of them are
     high-quality. Project Fi automatically connects you to more than a
     million free, open Wi-Fi hotspots we've verified as fast and
     reliable. This technology helps keep your speed high and your data
     bill low—whenever you're on Wi-Fi, you're not charged for data
     usage.

     Google Inc will pay $7 million to 38 states and the District of
     Columbia to settle an investigation into a controversial incident in
     which its Street View mapping cars collected passwords and other
     personal data from home wireless networks between 2008 and 2010.

   Since EFF has recently condemned T-mobile, I thought it would be time
   to condemn Google. This provides greater context to Google's efforts to
   collect data on wifi networks. Such a program would allow to create a
   database of ip addresses each wifi network uses, and allows  for a
   greater degree of mass surveillance.
