Generally people are ok with Facebook doing it because they can opt out.<p>If you notice, the times people really get upset about companies tracking their personal information is if it&#x27;s either not disclosed or it&#x27;s done in a shady manner.<p>Also, capitalist societies tend to treat state actors differently than private corporations.  It&#x27;s much easier to choose a new corporation to interact with and the state tends to have a lot more personal&#x2F;private data about you (which you&#x27;re required to share with them).
