Your view is flawed... With digital information you not only need to have a historical view of what Google as done with the data you've given to them, but a future view of what they
may do with that data. Remember, digital information never degrades or rots and lasts forever. Additionally, Google owns the information you've uploaded so even if you think Google is great today you may not think so in 10 or 20 years when Google and its data is now owned by some company using your data for reasons you don't like.
If you don't give a company a reason to exploit your data (i.e. don't give them the data to exploit) they can never disappoint you.
