I would argue that google employees are a much smaller issue:
- There are many less people (probably 2-3 orders of magnitude) accessing the data at all at Google, and (probably?) most sensitive data isn't accessible at all
- As you can't choose to avoid the government, the standard of trust should be much higher
- I don't know how well it works at Google. The reports of videogame leaks through employees accessing accessing unreleased Videos and the (for now) inability from Google to solve this problem at least indicates to me that the approach has issues.
- There are many more valid reasons for a government employee to access the data, so it's harder do differentiate. You also have the issues of police dempartments (and similar), where an access might not be allowed but done as unoffical policy "for the greater good"
- I would think that Google is much more capable of implementing and managing such a system than goverment suppliers or agencies, unfortunately
