An old (90s) parable Perry Metzger came up with - point being, they'll always use "heaven forbid, the children" as the final arbiter in removing all privacy rights.

"Meanwhile, the wise man talked one evening to his friends on how all of this was making a sham of the constitution of Ruritania, of which all Ruritanians were proud. "Why", he asked, "are we obligated to sacrifice all our freedom and privacy to make the lives of the police easier? There isn't any real evidence that this makes any big dent in crime anyway! All it does is make our privacy forfeit to the state!"

However, the wise man made the mistake of saying this, as the law required, in Ruritanian, clearly and distinctly, and near a microphone. Soon, the newly formed Ruritanian Secret Police arrived and took him off, and got him to confess by torturing him. Torture was, after all, far more efficient than the old methods, and had been recently instituted to stop the recent wave of people thinking obscene thoughts about tomatoes, which Dorothy Quisling noted was one of the major problems of the new age of plenty and joy."

It seemed absurd at the time but it's becoming a reality.

Note: I had to use Qwant to find that. Just sayin'
