The private sector has always attempted to know what people thought of their product, customer service, and to plan for the future. The grey are comes in when subliminal messages are sent, at specific times, and when the information is sold to others. This should be restricted to having a good product, good price, and good customer service.
When governments data-mine, it is for bad to wicked reasons. It is wicked under Fascism, when the government and the private sector, works together for control over people. Dan.12:4 "knowledge shall be increased". This type of "knowledge" is wicked. All of the "smart gadgets" operate off, or were created from this "knowledge".
This type of "knowledge" can be traced back to the Tree of Knowledge, of good and evil. It is connected to Idol worship, and control of people. It is also responsible for new books, including new bibles; for good reasons, the Lord writes in our minds, and the Holy Spirit speaks to our minds-and Satan knows it.
Satan's children knows that it has the world. The Saints operate inside of the Kingdom of Heaven, on the earth. The wicked doesn't really care what the world thinks, but must attempt to Data-mine in order to know what the Saints are thinking. It must separate the Saints from the cants.
The first beast of Rev.13 is a one-world-political-system. The glue that holds it together is fake money, and fake power. The federal agencies that are Not mention in Constitutions are living wild beast. Branches, not-pruned, will take power from other Branches. All of the recent [5 yrs.] information, collectively will cause the "deadly wound" in Rev.13. The Data-mining will prove to be self-destructive.
