In order to "flag" a document they must be scanning it and running it through an interpreter that looks for keywords and phrases. The users experience with their documents being flagged makes it obvious that Google is scanning every document you create/store there, so the curious mind might ask "why?". Now, we can all try to believe that Google wouldn't steal from us, or turn us in to government authorities if they saw something that they believed was "unpatriotic", but what if we found out they're getting paid to do that by governments all over the world, or what if you saw some amazing new tech you've been working on suddenly appear from Google? Could be they're "doing no harm" to anyone, but it might be naive to believe it. Google is in the business of making money. That is what they do.
