There are countries where people go to jail over Facebook or Twitter comments and even just using it could be triggering some arcane investigation against you.<p>Also Iran (likely others) did try to inject tracking JS in plain HTTP and they got the ability for a while to have valid certs so HTTPS is not really helping if you are not really paranoid with certs and hashes that is really difficult to archive.<p>Once you got Tor running and connect to an onion you have quite a few guarantees that are hard to circumvent&#x2F;spy on for a government.<p>&gt; by that I mean you think people are planning terrorist plots over facebook? come on.<p>It sure has likely happened. Due to Facebook only access (internet.org) for a lot of the world using mobile and Facebook is the only access to internet that is affordable. Online shopping is also handled over Facebook in these countries.<p>While Facebook shares your data with courts it has no way of knowing  who you are if you are using Tor. At least it can&#x27;t forward your location to the local secret service to beat you up. A somewhat qualified court request from a western country is also something different than arbitrary repression from dictatorships.
