            Paranoia is not synonymous with security, nor is it synonymous
            with "privacy."
    
            Hacking ps to fix a security problem in ppp is not the solution:
            fixing ppp is. ps(1)'s -a and -e flags were implemented for a
            reason; to remove them is de-evolutionary.
