Smoke and mirrors
I hate to break it to ya'll. Especially as you most likely know it anyhow, but this really isn't worth wasting typing time on. Unless of course, you want to spend time discussing the finer points of a certain level of civil servants keeping themselves amused.
There is no online security, once you're on you are out there, and nothing devised so far is inaccessible, or unbreakable to those that have the gear and will to do it. And certain entities have a lot of gear. And they have the will.
The only way you can tell a secret, or even just have a private conversation is to talk to someone face to face, in a place that is difficult to eavesdrop.
The days of privacy, and respect for privacy are gone - if such a time ever existed.
In fact its ludicrous notion to expect to be connect to the 'world' (not the nice one on the other side of your office window) and to assume that those connections aren't monitored. It's like walking down the street naked, and not expecting anyone to notice you have a little tinkle.
So go take a walk, get some fresh air, accept that this technology doesn't only empower you. Just remember to put some clothes on
