Government access to your data alone is enough reason for me to reject a backdoor. Seems a clear avenue for 4th amendment violations to me. The only way to keep the government from even further violations of the Bill of Rights is to ensure that they cannot physically do it, because the government absolutely does not pay any attention to its constitutional limitations.
BUMP! Like your thinking. You are right on the button.
Government spooks have even shown themselves incompetent to keep their data private to themselves.
Why should we ever want them to have a back door; what’s more even if they could, the market would soon find other things that would shut it, and the back door would languish.
If we had a government that would better honor the God who DOES know everything, we would have one with much less desire to engage in comprehensive snooping.
