Schools are at fault, not Google (Score 1)

The real problem is the school administrators loading all of the student's personal information into the devices, using poor privacy and security practices, not taking the time to understand what they were doing with the Chromebooks, and then blaming Google. Read the article. Here's a quote that sticks out:

"schools had mass-enrolled their kids into Google email accounts, using their full names. Furthermore, they posted photos of them on social media sites and enrolled them into other services that collect data without any notification. To make matters worse, the passwords students are assigned are easy to guess, featuring their birthdays or student ID numbers, which makes them extremely easy to guess. Students are also prohibited from changing their passwords."

Those are all actions and policies undertaken by the school administration. It has nothing to do with Google, except that Google provided them with low-cost (or often free) devices for the students.
