Simply as an observation, I would be legitimately shocked if the FBI didn't use these same techniques with automation to find suspicious torrents and get data from ISPs.
It's a joke, but nothing protects you from being officially asked that.
The state of moral panic in which everyone is supposed to agree that “protecting the children” is a wild card which only complete deplorables dare to question resulted in what has been predicted decades ago. All around the world, governments and corporations have lobbied censorship infrastructure for themselves in the name of the children. It's written right there in the laws, as if straight from Four Horsemen of Infocalypse Wikipedia article. In addition to that, Internet is subject to semi-legal de facto “agreements” based on ever-reaching US laws. It's because of these agreements between dealers on the shady side of the net (and their connections elsewhere) you don't see child porn advertised just as often as regular porn. A lot of people wouldn't hesitate to make lots of money on the hottest topic.
That's something they have in common with other professionals. Murder (of a person of any age) results in a couple of regular news flashes, some mentions on roller captions, and that's it. However, add sex (or sex with children!), and you'll have a media goldmine. And, of course, there will be some politicians proclaiming it's the right time to ban encryption. But they can do it only because everyone react the way they react.
