After I see how the sausages are made, I think claims like these are naive. It's worth learning more about the factors at play before criticizing something. More often than not, the agents are acting pretty rationally based on the situation.

All of these concerns could be trivially addressed by leaving them up to the user. Add the necessary controls to the user account page, pick default settings biased in favor of privacy, and allow users to change them if they prefer.
