The harm done by surveillance societies is not completely subjective. People are suffering. Their suffering due to surveillance-pervasive society is objectively bad. And if you want to argue that people should suffer and that is a good thing, we have gone off the rails into a discussion of morality, a discussion I would be shocked to have here.

I think it is safe to say that intentional and targeted suffering of minority groups directly due to our surveillance society is objectively bad. The only wiggle room here is, as you said, the existence of people who believe that targeting minorities for suffering is a good thing but I surely and dearly hope that we can still call those abhorrent ideas "objectively bad".
