So we all know that NSA has the ability to track down Tor, I2P and all those anonymous networks. I know it's a piece of old news, but the question always shows up in my mind. Which is why bother it? I mean all your communication is encrypted through public key cryptography even through the simplest HTTPS connection, so apparently, they can't see what you're sending through the network. So unless you're visiting know illegal website, they shouldn't be able to track you down isn't it.
Like if you're talking with your friend through FB's Messenger, let's say. There's so much traffic in and out through FB's servers, how would they be possible to identify that this traffic is between you and server and then track you down to your location by the IP exploit from the connection (as it's one of the few stuff that isn't encrypted).
If that's true, then why bother if NSA has the ability to de-anonymize Tor network. Or even simpler, why should you use Tor network there isn't any difference between standard HTTPS anymore? Plus, they still can't identify you out from that pool of connection through FB server and with a Tor it might even standout from theirs view.
