But that’s exactly their point: it it’s legal for them to bug your house when all prerequisites are met. That last part is very important. Without voicing my opinion: that is the current law in many western democracies.
End-to-end encryption means that even with very stringent limitations, they would never be able to listen in. None of the previous spaces “beyond their reach” has been that.
And BTW as far as I know churches have never been this, legally. There was a time when you could find asylum in a church, and you couldn’t be arrested, but they were never barred from law enforcement listening in.
And, for the record, this part is my opinion: end-to-end encryption should be possible, and without backdoors.
