Internet protocols were originally set up with 2 driving ideas.
1) We are all friends here.
Developed by ARPA to allow researchers on ARPA projects to share computing resources
Sure you can peek at the packets you're trans shipping to someone else but you don't want to.
2) Encryption is expensive
So if you can't encrypt everything why bother? See also point 1.
But that was a world where the internet backbone was 56.5kbs and 8MB of 50ns memory put you in supercomputer territory.
Today real time encryption is possible (although ensuring the implementation is secure is not trivial) and the internet is no longer the sole property of the US Government.
Thanks to Snowden we now know as an absolute fact that major governments can monitor anyone they choose to, and so far (because the protocols have allowed them to) they have chosen to monitor everyone.
This rampant fishing trip mentality, where "innocent until proven guilty" has gone out the window (you're all guilty of something, we just haven't worked out what yet as an NKVD official might have put it in Stalin's time) has got to be stopped.
Societies should be able to defend themselves, but what we've been seeing is that the states they have created (or parts of them) seem to view the society itself as the enemy and peoples desire for privacy to be wrong because it prevents them from knowing everything about them forever.
Accept you can't have perfect security even in a prison, which seems to be what some spooks are keen to turn their countries into. Then let them go back to finding real threats, that actually buy stuff and talk to each other rather than this FUD BS which they seem to use instead of acting like proper investigators.
