Not to mention, Companies. Would you want your internal documents stored on Google Cloud where it could be "read" or even sent to a 3rd party ?
The answer appears to be a resounding "Yes, as long as you don't force me to consider the implications."
I think you'll find that today, the majority of corporate IP from the western world has found its way onto the Google Cloud. When corporations lock things down so tight that it becomes a day's endeavor to send a spreadsheet from one office to another in a large corporation, people tend to give up and use gmail. When you're a small shop and can't afford the resiliency that's a requirement in this day and age, you're willing to risk the perceived small chance of losing your IP for the pure fact that you can afford to do business using Google Cloud.
So would you "want" your documents stored there? Probably not. When it comes to pragmatism however, most companies and/or at least a few employees let pragmatism win out over privacy concerns.
That would be nice.. But my company DOES care. They block access to Goggle Drive and DropBox type sites (and you can be fired if you send emails with corporate docs to other sites/people).
