Better you upload your unencrypted data to a third party you know about, than that some hacker collective uploads your unencrypted data to pastebin for you. I think Sony pictures would have been quite a lot better off if their data was all on Google drive and Facebook.

Sony was probably the victim of an insider (http://nypost.com/2014/12/30/new-evidence-sony-hack-was-insi...).

It is incredibly difficult to prevent attacks from technical people inside your own company, and when this happens to a company like Google or Facebook it will be a huge disaster.
