All those negative things are happening in a society that implemented mass surveillance so clearly it doesn’t help. Recording a crime doesn’t prevent it and if there’s no incentive or funding to make sure justice is served afterwards the recording is useless. I think you’re mistaken in who this surveillance is for: it doesn’t exist to improve your life but to empower corporations and state against you.
I would also like to know how you did that because as far as I’m aware Fairphone is not supported.
