‘You have nothing to worry about if you’ve done nothing wrong’ is the response many people use to scorn those concerned by the scale of modern mass surveillance.
And this is the best response such ignorance:
You’re giving up your rights. Your rights matter because you never know when you’ll need them. People should be able to pick up the phone and call their family, should be able to send a text message to their loved one, buy a book online, without worrying how this could look to a government possibly years in the future. We have a right to privacy. Trusting anybody, any government authority with the entirety of human communications, in secret, without oversight, is simply too great a temptation to be ignored.
The best of intentions can always be corrupted by the self-interest of the dominant group, and the individual will suffer. An individual’s right to privacy, and a right to be forgotten are both sacrosanct in the digital age.
