It is interesting how you think. I'm pretty sure that most legal precedent is based upon a certain set of inherent/inalienable rights. In fact, the entire argument you are putting forward is based on the fact that you believe that you have a right to privacy. Ok. Where did that right come from?
To think that rights are "granted" by a organization or entity above you is the definition of being a subject ("you have the freedoms that they say you have"). To think that I have rights without any sort of government/organization influence is being a citizen ("you have freedom, other than the limitations on that freedom that they have instilled).
So which is more "free": 1) providing the framework to barter information for the use of a good or service, for which either party can choose to not take part in or 2) force one private entity to provide goods and services without compensation to another private entity through the use of the legal system.
But in truth, this discussion really is rather pointless.... the majority of people really do not care at all, and are perfectly fine with letting the "world" know that they like golf, kittens, and game of thrones. If that was not the case, then DuckDuckGo would be the top search engine. Are you angry that the "internet corps" are using the income generated by this "invasion of privacy" to facilitate the infrastructure of your blogspot.com blog? You do realize that is Google right, and they know that you like Kayaking because you wrote it on their servers?
