[...] but I'm also a believer in that if you've done nothing wrong, you have nothing to hide.
The thing is, you are wrong. Everybody has something to hide. And the stuff your neighbor or your friends don't need to know, the government certainly doesn't need to know.
But that is not even the real issue with these things.
The thing is, if the government knows everything about you, you can be manipulated. If you know you are being listened too, you will choose your words more carefully or not say certain things. It undermines the rights of freedom of speech, freedom of assembly and freedom of association. And by that, it directly undermines democracy. These are very, very Bad Things™.
Unfortunately, most people don't realize this and not speak out or otherwise try to do something about it. They will when it is too late, but what are you going to do when it is too late?
First they came for the Communists,
and I didn't speak out because I wasn't a Communist.
Then they came for the Socialists,
and I didn't speak out because I wasn't a Socialist.
Then they came for the trade unionists,
and I didn't speak out because I wasn't a trade unionist.
Then they came for me,
and there was no one left to speak for me.
A good talk on the subject of security and consequences:
