Needless surveillance is treason
If a republic or democracy is empowered by the citizenry, but doing something which is not in the interests of that citizenry then it is the government that is acting treasonous. Is mass surveillance in your interest?
Is mass surveillance misused? Is it likely to find what is not there to justify itself? The government does not function for itself. If it is maintaining 'sovreignty" at the expense of your's, that government betrays the reason for its existence.
Governments which cannot be bothered to maintain databases correlating birth certificates to death certificates, or keep accurate demographics want to see your dick pics for terrorism. Seem legitimate to you?
