 This separates private communications from the ability of a private for-profit or non-profit organization to corrupt.Security for the individual is in this way protected by the United States Post Office, maintaining confidentiality and anonymity, as well as government employees being much less likely to be instructed by superiors to engage in nefarious spying.It is seen by some as a dangerous step to extract the universal service principle from the post office, as the untainted nature of private communications is preserved as assurance of the protection of individual freedom of privacy.
