The data isn't being used, yet. As safeguards continue to erode and storage becomes more massive it's impossible to think it wouldn't be used improperly. I'm no fan of trump, but what would the Mueller report have looked like if every site he visited and phone number he dialed and text message he had sent since he was a child was stored in a US govt server they could've just walked into. If you don't see this is a system that will destroy our advanced democracies through perfect surveillance and blacknail, then I question the amount of thought you've put into this area.
