I'm not worried about my government as it currently stands. I'm squicked out by the fact that every single private company I interact with seems to be falling over themselves to collect as much data about me as possible, and resell it to anyone who will pay. There are no protections against this in the US. I am worried, at least a little bit, about an authoritarian government coming to power and basically weaponizing past data collected against it's citizens. I've seen the inferences facebook and google can make with privately collected data. I don't think it's too outlandish that governments would be able to quickly and easily create detailed dossiers on everyone that protested against x or voted for opposition candidate y.
