UCKING BUYS THE DATA WITH THE TAX PAYER MONEY to spy on them
I think you have it backwards. Look at "Digital Life Log" by DARPA and it's connections to Peter Thiel, Palinter and Facebook and you'll realize the government doesn't buy the data. It funded/created all the companies that collect it for that specific purpose.
The CIA literally has a startup incubator fund called In-Q-Tel.
