So if it is not worthy of your attention, why do you feel the need to post such a long diatribe against Google? I find it funny that anyone who engages on the internet is worried about privacy and tracking...you signed in with an email to post here, didn't you? It's fine that some people are too uncomfortable with the thought of tracking and keyword scanning to use web-based services, but it's obviously a trade-off that many people find very beneficial. The free services you get for allowing ads targeted to you are amazing.
I personally feel like people worried about others seeing their data are really oblivious to how insignificant they are on earth--automated bots are using algorithms to track and scan--no person is looking at your data because nobody at Google or any other cloud service could care less about you as an individual--and for those who know people at Google, it is strictly prohibited and illegal for an employee to try and get past the security controls that prevent them from spying on an account.
The only real concerns with cloud privacy is that if A) you don't do enough to protect your password and at the same time do not use two-step authentification to prevent your account being accessed remotely and B) if law enforcement ever targets you in a criminal investigation and gets a search warrant for content stored online--it would be the same if they burst into a house withe a warrant and confiscated files and hard drives.
