the issue is not with the technology, but with people, as always. with the adoption of ipv6, iot and gps_in_everything etc. it's not a question about if the technology can be used for bad things, it's a question about if it will.
people who only believe int he darker side of this technology can easily avoid it by not participating. they should let people who willingly participate do so at their own 'peril' if that's their opinion.
privacy advocates are the new religion trying to push their views on everyone even though it's just a matter of opinion. some people love to be tracked everywhere for the benefits it can give them, other people hate it for the downsides it might have. its all a matter of opinion for users, and a question of integrity for its masters.
