Fundamentally though that's the problem with the modern web - the services that users get is not a transaction in the sense that the user knows what they're giving up for the service - it's all hidden under an innocent permissions check (if it's Facebook) or not said at all (if its LinkedIn). The user provides permission for a small pittance like their email address or phone number and it snowballs into having every want need and action tracked and catalogued to make the service owner money. A product not intent on tricking the user into giving up every bit of the data on their life would ask if it could use individual bits of information to serve them ads and sell their information.

It takes more than it asks, and the fine print is there to cover its ass, when in reality if users were asked about what information they were willing to share they would be much more uptight. The users's have no real idea what is happening with their data, what they've given up or how its used to make the company money. It may be true that most user's don't care, and some might even prefer the outcome to them in the form of "relevant" ads (if the choice is made over "irrelevant" ads or paying for the service). It certainly is transforming what is in the public sphere about people, and the lessening of privacy can certainly be used as a weapon (and it is, to the extent that it is a big powerful force arrayed against a person independently figuring out what they want to spend their resources on).
