I agree with what you are saying. Google undoubtedly puts a lot of emphasis on security and privacy against external threats. In other words, it is unlikely that google systems would be hacked and user secrets be leaked. I can be relatively confident that script kiddies won't hack the Gmail servers and download everyone's data.

However, Google most definitely puts no value in privacy in the holistic sense of the word, because as you say they'll willfully harvest every last bit of information, sensitive or not, that users store at Google. Google cannot be given a shred of trust with private data, because they have time and time again demonstrated to have no moral compass in this respect.

They may take a lot of care about protecting this data from others, but they don't care at all about protecting the data from themselves.
