What this argument ignores is context. The ethical landscape shifts when you consider that Facebook is in a monopoly position of power over a major aspect of modern life and culture. The user's decision is not about using or not using Facebook. It's a decision about whether they can participate with their social groups, or interact with certain businesses (who are also hostage to this monopoly), or help out their local charity organizers. In some regions, it's a decision about whether to gain access to the Internet at all. Reducing the decision to a reading of the TOS, imposed by this monopoly power, ignores this glaring context, and fails to ask another important question: is the business model itself ethical? And as others have pointed out, one need not even be a Facebook user to be subjected to their tracking, which is the tip of the iceberg in terms of their less than ethical behavior.
