One doesn’t do this unless they have an unhealthy relationship with sexuality and porn:

he and his teenage son monitor each other’s every keystroke in an effort to make sure they don’t expose themselves to pornography.
This was recently revealed in a clip that was posted by the user Receipt Maven on X. Last year, Johnson spoke on a panel during a “War on Technology” conference sponsored by a Baptist church in Benton, La. In it, Johnson enthusiastically endorsed a surveillance app called Covenant Eyes. The app, which is promoted by churches and other conservative religious groups such as Promise Keepers, has users designate “accountability partners” to hold them to task in the event they stray into illicit digital outer space. Often the accountability partner is a pastor or fellow church member.
Covenant Eyes, which costs about $15 a month, takes one screenshot per minute, Wired reported last year in a story about what it called “anti-porn shameware,” which is a multimillion-dollar industry.
Johnson’s accountability partner, he said, was his teenage son Jack. Once a week, he said, he and Jack receive a report of what the other has been doing on his phone, laptop or tablet.
“If anything objectionable comes up, your accountability partner gets an immediate notice,” Johnson said. “It looks for keywords, search terms and also images. It’s really sensitive.” Johnson said he once got an alarm about Jack’s questionable internet usage involving a blurry image of two women. “I had to zoom in on it and unblur it,” Johnson said, “and it’s two middle-aged teachers.”

I suspect the only way he can stop looking at that sweet sweet man-flesh on the internet is knowing his son is looking at his screen over his shoulder at all times.
