I think it mostly matters in the context of US case law, specifically the third party doctrine. > The third-party doctrine is a United States legal doctrine that holds that people who voluntarily give information to third parties—such as banks, phone companies, internet service providers (ISPs), and e-mail servers—have "no reasonable expectation of privacy" in that information. A lack of privacy protection allows the United States government to obtain information from third parties without a legal warrant and without otherwise complying with the Fourth Amendment prohibition against search and seizure without probable cause and a judicial search warrant. https://en.wikipedia.org/wiki/Third-party_doctrine https://en.wikipedia.org/wiki/Third-party_doctrine
