How do you "act accordingly" when you want to partake in sharing digital private documents with your wife? In order to follow that advice, you'd have to stop using smart phones entirely, and that's not really feasible today.

Sure, it's lurid in this case because it was nudes, but this could have just as easily been identity theft or something more mundane but equally wrong for Google to access.

No, this is what we have laws for. What Google did is wrong and if the person responsible cannot be criminally prosecuted, we should seek legislative changes to enable prosecution in cases like this in the future. This is not merely a matter of individuals trusting Google too much. The individuals don't have much choice; that's where the law can step in.
