Dark Mail (as profiled) is an earnest effort to circumvent NSA-snooping (in the post-Snowden era) whereas privacy concerns are paramount (despite the unfortunate overall degrees of global, public apathy / indifference, etc.) In sum, civil societies rise and fall based upon civil liberties… and, the path that’s been undertaken post-9/11 has been (unfortunately) oriented to the latter (not the former)…
