> Google's business model is based on selling user-generated data to advertisers, unlike telcos who sell network data to you.

Sure, because the telcos have no interest in tracking their customers for profit[1]? As long as it's profitable and legal, any public company will eventually sell metadata regarding you. Since the data is profitable, if we want to protect ourselves from this that leaves us with making it illegal to collect and share, either through contract or by law.
