Many nations now seek to monitor communications of their entire populations (UK plans are reported here - link). The State can access our information; they try to assure us we're thus better protected.
Internet and telephone provider firms are forced to pay for surveillance & storage equipment, costs passed to consumers. These ludicrous systems will cause many multiples more problems than potential successes. The banks & credit card companies are already thus regulated, but at least (because of the money) security & secrecy are part of their basic mandate.
Giving anyone access to such telephone, email, and computer interactions is monstrously problematic. Under existing & proposed laws, private sector providers will be required to store data for many months or years. From a security perspective, your data is at grave risk of hijacking. Technical entrepreneurs are sure to hugely profit from some such files or metadata. Resale? Blackmail? Piracy? Government snoops are angelic in comparison.
We'll soon be hostage to minimally-trained private sector tech staff who recognize the value of information they collect & control.
