Yes. But my point is if you have a survey of this nature and both google and apple ace it then you have learnt nothing. Because Apple and Google are light years apart in terms of how they treat customers personal data.
And exactly what difference there is between how Apple and Google treat customer personal data?

It's about protecting your privacy _against the government_. Now with Dropbox I would seriously expect them to keep my data private against anybody (including Dropbox), because that's their business. Facebook and Google, less so.
Google's business relies on having your data secure.

However the cost in terms of my profile and personal habits that are made available to others is much higher than the with Apple that also gives me mail and an office suite for free but does not make my profile available to others.
And exactly what is made available to others?
