I don't. Usually, that comes from our leftpondian friends. It is correlated with authorian gouvernments, and those are still not as widespread here as some people from "over there" wish for. Sniffing out every citizen is something dictators do, and we had our share of those.
Beware simplifications. Yes, sniffing out people is something dictators normally do. But the rules have changed.
The Internet is still a US thing. In the US it was normal for a businessman to use Compuserve, already back in 1985. In Europe such was very rare.
For the masses, having an online access became possible as late as 2000. As then still the commonsense was, we don't want computers, we don't need computers, they are nerdy stuff we're not interested in. The only thing internet access was desired for was to watch porn.
Obviousely this has changed in the meantime. Internet is now considered a good thing, it is considered the future, it is absolutely great for anything, and is an unquestionable necessity. And this view is just as uneducated and undifferenciated as the refusal before.
And government has started to force people to use internet: even the smallest shop must report their tax declaration online (consequentially prices for services have doubled - somebody must pay the computers).
And now normal society schemes are projected onto the internet: like in society there are mostly honest and trustworthy people and a small amount of criminals of which police will take care, also the internet is mostly trustworthy and police must take care of the exceptions.
For instance, people have figured that they no longer need to educate and care for their children, because the Internet will now do that for them; they just need to hand their sucklings a smartphone.
Then the big surprize was, there are indeed certain people on the network who would care for kids left alone - and that was then called sextortion.
Now that is where the fun begins, because now the "ritual satanic child abuse" is back. Formerly satanic child abuse was a hoax, an urban legend - and while metalheads, magicians and satanists all together would just laugh about the allegation, typical gullible do-gooders were greatly worried.
But now the child abuse is back - and to keep up with the dream that the Internet itself is all good and trustworthy, the disagreeing vectors have to be labelled as the archetypical evil: it is not simply a crime (or rather a temptation: leaving your kid alone on the internet is no different to leaving your purse alone in a public place), it must instead be a weird mixture of everything establishedly evil one can think of: fascism, satanism, totalitarian sects, organized crime, etc.etc.etc.
And so, obviousely, the police must take care of. And the police themselves, also, want to take care of. Only now they find out, that is not so easy, especially when one has cultivated a habit of not-wanting-to-know anything about the Internet for decades.
So now that is an issue where the government must do something. And that is where we come out with the demand for backdoors in encryption.
The whole thing is obviousely the typical scheme of utilizing fear to justify repression: the risk that somebody might steal from the rich does not establish fear, the risk that somebody might abduct your children does.
And that scheme is not limited to dictators; it is quite popular with any people in power who have no idea about what they are actually supposed to do: they want control.
