Society fundamentally changed with the introduction of computers. Things have become possible that were never possible before. This is obvious if you consider the tech of 1900, 1950, and today.
The elephant in the room is that the more complete the dataset the more dangerous it is. Its like gunpowder. Firecrackers are sold without license, small amount of gunpowder. Dynamite and other explosives with larger amounts of gunpowder are heavily restricted because of the damage that can be done. Today, there are laws against re-packaging explosives to protect people.
I believe the damage that these datasets are doing to society are covert and second-order effects that are hard to track. Most datasets like what the NSA are doing are kept secret precisely because they don't want transparency. If there was transparency, the damage would become obvious that regulations would swiftly come.
