Facebook tracks people who are not users. That has been a reason for lawsuits. I have taken measures to block Facebook trackers in many sites I visit. So yes, Facebook (among other agents, like Google) is forcing me to follow a course of action that protects my family and myself from intensive data collection, and that many times breaks my browsing and interferes with my work. Forcing HTTPS, blocking cookies, revoking certificates, etc. and then reverting some special cases or creating exceptions on the fly for specific sites I cannot go without is kind of maddening. Stalking isn't a relationship, but it does force victims to take action.
