Yeah, these things are scary. My test for people who ask for these backdoors is to ask for them to hand me their unlocked mobile. I promise to not share any information I read/see. There is an expression in this area that I love (but I can't remember the exact phrase): If you follow anyone around for some small period of time, you will find them guilty of breaking the law.
"If you give me six lines written by the hand of the most honest of men, I will find something in them which will hang him." - Cardinal Richelieu (disputed)
Back in France at the time of Richelieu, there wasn't a concept of free speech or religious freedom. Thus if you said that you thought the king was an idiot, you could be hanged. Or you doubted the Church, or doubted God existed.
Remember, blasphemy could be punished by death at that time.
Nowadays, in most free democracies you are free to say you don't believe in religion, or think the leaders are idiots and there are minimal consequences.
