The boundary should be that user generated personal data that is on a user device should stay personal on a user device unless explicit consent is otherwise given. That's it. The argument is always well "don't you want to save the children" to which I give this example. In the USA guns are pretty freely available, relative to other countries. There is a huge amount of gun violence (including shooting at schools targeting children) yet every time major gun restriction legislation is introduced it fails, with one major reason being the 2nd amendment of the US constitution. This could again be amended, but sufficient support is not there for this to occur. What does this say about the US? They have determined, as a society, that the value of their rights is worth more than all the deaths, injuries and pains caused by gun violence. A similar argument can be made regarding surveillance and child porn, or really any other type of criminal activity.
