I see this a lot on here: "We can overcome this through legislation and a focus on privacy..."
Its just not True. This type of pervasive surveillance has little to do with what government we have, who is in power or where they money is at. It all comes down to progress. As we move forward and advance technology this becomes an inevitability. Even a societal move to neo-luddism won't help long term as with all luddite movements the people eventually die and their kids, born in the technology, are less scared of it.
Yes, we can push back, regulate, ban certain technologies, but its all an uphill battle. The advances in technology far outpace our ability to protect privacy.
