That's one of the main points about bitcoin for me. As a tool for privacy. On the surface it may seem trivial, and corporations living off mining your information will always try to pretend it's not even an issue by simply avoiding mentioning it. While at the same time push for their payment solutions as either compulsory or cheaper ("soft pressure"). But make no mistake, this is one of the most effective tools for mining your data reliably and the likes of Google, Facebook, Amazon, etc are just not going to give up on it easily. Authorities also won't give up on "follow the money" as a tool, or even snooping and hacking into your communications legally or not, inside of their jurisdiction or not. It's basically no rules for some, all the rules for you.
