Ten years ago it was "unfortunately we have to infringe on your civil rights due to terrorism." That excuse has since been overused and isn't as blindly accepted anymore, so clever politicians and their bourgeoisie patrons have moved on to "unfortunately we have to infringe on your civil rights to save the children." It's the same excuse behind the EU wide proposal to effectively neuter encryption in communications services, and it's absolutely bullshit. Law enforcement agencies already have the capability to investigate and stop the vast majority of child sexual exploitation, but they don't get the resources required nor the priority. A healthy society would likely take care of whatever would slip through the cracks. Breaking encryption or free access of information does absolutely nothing to stop this behaviour, and in some ways would put children in an even more dangerous position.

Tldr: this is about controlling the plebs, not about protecting children.
