Does anyone really believe their metadata is safe from any government... or non-government for that matter?

I mean, TFA's whole argument is the un-encrypted header portion, designed to route the message, can be used to track who the message is sent to. Oh, and some dude provides internet service to Russian governmental agencies with their ISP located in Russia.

If you're doing dodgy stuff (like political speech) you don't want the government to know about it's probably best to conduct that business offline as they are all watching you.
