This BS is allowed by "Third Party Doctrine" which means that once you give information to a third party, you no longer have a legitimate "expectation of privacy" so therefore you don't have one. For example, if I want to pay you $100: - I can give you $100 directly in cash. We can limit that knowledge to two people, therefore it could remain private. - If I pay you via check, credit card or Paypal, now I've involved a third party and the government can collect any information they want. It's up to that third party to choose not to share it. Check out the book "Habeas Data" if you want to understand the US rules - and how we got there - https://amzn.to/311a0yl https://amzn.to/311a0yl
