As you may have read, Google fired an engineer who accessed private data to find the email accounts and phone records of several minors he had befriended. This is an obvious and inevitable consequence of Google aggregating so much private data–the risk that those who want it, and have access to the information, will use it for inappropriate ends.
As I wrote in Omniveillance:
When I wrote this, I had in mind hackers stealing private data from google for nefarious ends–but this passage applies just as equally, if not stronger, to rogue agents of Google who misappropriate this data.
If Google did not make this firing public, it is likely that we would never know about this breach. Further, there are likely countless other internal breaches of data that never see the light of day. To quote omniveillance once again:
Short of Google’s self-proclaimed goal to do no evil, it has no legal incentive to protect privacy in America.
If Google is guarding our data, who will guard Google? Quis custodiet ipsos custodes?
