Why is the content of your document of any relevance to the service? I don't care if they scan your shit for targeted advertising, but if they start censoring you, that's a whole different ball game. Google is a monopoly with a political agenda who contributes millions to particular presidential campaigns. This should be a red flag that it's basically an extension of the government using a "private company" loophole to get around the constitution.
No, Google does not have a monopoly on cloud storage services. If they decide you've violated their TOS and remove your content, that is not censorship. I mean, it's certainly very obnoxious if they start removing content without telling you why, as is discussed in this article, but if they do you have alternatives.
