"Saying you don't need privacy because you have nothing to hide is like saying you don't need freedom of speech because you have nothing to say." - Edward Snowden
"Saying you don't need privacy because you have nothing to hide is like saying you don't need freedom of speech because you have nothing to say." - Edward Snowden
The meaning is to highlight the incredible silliness of the “nothing to hide” skawkers who sound like so many Soviet propagandists.
Then move on to the fact that not every govt employee is honest. Some will be involved in organised crime. What about your family do you not want organised crime to know? Do you trust everyone in the government who might encounter you today? Do you trust everyone who might encounter you next year? In 10 years time? 20 years? Gotta trust them all!
The rule of law exists, in part, so that the strongest does not always get their way. Do you trust your insurance company and their outsourced contractors with knowing everything about your family when they refuse to pay your legitimate claim and you have to go to court? They have vastly more resources than you already.
There's plenty more, think them through.
By the time you have it that these people who don't care, they also don't want to be naked in the street or have their children be naked in public, do want freedom and democracy rather than soviet style tyranny, and don't want to be effectively targeted by criminals... If you need to continue, it's a lost cause and you're dealing with bad faith or total un-fixable idiocy.
Thinking comparisons of two similar things are always for the purpose of saying that they are the same thing is ridiculous, don’t you think? It might sound like clever reasoning to people of a mediocre intellectual capacity but it is not logically coherent.
Surveillance suppresses expression through chilling effects.
EDIT: IIRC Brin addressed this in his fictional treatment of the concept in the novel Earth
How does that even help? The concern is that you're deterred from e.g. admitting that you're a lesbian under your own name because your religious grandparents wouldn't approve, or advocating for school choice because your boss is married to a public school teacher, or criticizing the government.
Knowing that they're going to see it doesn't stop them from cutting you out of their will or putting you on toilet duty or playing "show me the man and I will show you the crime".
Think cops with always-on cameras, not grandma poking around beneath your mattress.
