The world governments are getting so worried about Google capturing private Wi-Fi data like username and passwords! However, they are forgetting two things. First, Google is not doing this using some exclusive uber-gizmo it solely owns that can crawl into the Wi-Fi and extract passwords and usernames and secondly, users are supposed to use encryption on networks as a basic protection.
Wi-Fi data is the most vulnerable form of data because it is open-to-air. It is almost like a radio station and is open to anyone who wants to connect to the hotspot. Most of the time, these networks are unprotected and with the right tools, accessing data over these networks is childs play. That is why, Wi-Fi networks are the favorite spots for hackers.
Google captured Wi-Fi data, true. If there was encryption, the users could have safeguarded their data. However, in reality, it is also extremely easy for anyone to capture your Wifi data, i.e. anyone much low-tech than Google.
To prove just that, Kole McRae at techvibes has carried out an operation to demonstrate the process. He has been successful in extracting usernames, the accounts being contacted to at the other end, the browsing history and a lot more. My point being, there is a single user doing these things and there is Google doing only part of this. While people tend to ignore these petty data thieves, why should Google faces the heat for speculations (now established facts) of username and password captures?
