Surveillance facilitates social control, and spying will only make this worse. Governments around the world already use mass surveillance; they will engage in mass spying as well.

Mass surveillance ushered in the era of personalized advertisements; mass spying will supercharge that industry...The tech monopolies that are currently keeping us all under constant surveillance won’t be able to resist collecting and using all of that data.

We could limit this capability. We could prohibit mass spying. We could pass strong data-privacy rules. But we haven’t done anything to limit mass surveillance. Why would spying be any different?
