Overreacting is equally dangerous, I could argue that if they were really killing the freedom to communicate we should fight them as we would fight an enemy, possibly going to war, armed.

That's not what's happening here.

It might be useful to remember that our communications have never been encrypted before a few years ago and they haven't been less free.

Also: encrypted communication but clear text metadata kinda defeat the purpose of encrypted communication.

If I know where, when and who was involved in a call, I can easily tell that two people chatting and ending up in the same place every time both their partners phones are away from home, could be cheating

If I call an ambulance at the same time and place where an accident happened but the ambulance doesn't report a second vehicle, guess who probably didn't report an accident?

Privacy and secrecy are a broader subject, it's good we discuss about it, it's not good to blindly trust WhatsApp or Facebook with our data.

Bad as it might be, I have more control and trust more my state than a private company on the other side of the World.
