Hmm, this points out to me the main reason why a cellphone on every person and a shadow Facebook page for every non-user hasn't already abused free will past the breaking point: The amount of data, and the noise in that data, that comes from all those sources is so stupendously large that it's got remarkably little use as of yet. For the most part it's only useful for making the marketing/advertising industry slightly less ineffective, supplementing in-person stalking, character assassination, and finding low-confidence 'evidence' of crimes and infractions against ideological conformity to punish after the fact.
The current nigh-uselessness of general surveillance will change in the future.
I can't claim to have much more insight, beyond commenting that the origins of the technology matters. I think it's vastly underrated how much of society becoming more incomprehensible and unpredictable traces back to how much of our technology gets invented by private interest groups to make money, or serve questionable political goals, than to fulfill genuinely felt needs in the best way possible.
Incidentally, I am just now working on something that has to do with their father and the relationship he had to his kids... (Coming soon, shortly before Christmas!)
