It can be argued that a telecom system that you believe to be reasonably
secure (but may actually be subject to monitoring exploits) is
fundamentally more dangerous to its users than a totally insecure
ordinary analog POTS phone environment.
The reason is psychological, not technical. If persons are speaking
on an ordinary POTS analog line and are concerned about their subject
matter being overheard, they tend to be very careful about the
topics under discussion, or at least the explictness of their
language.
On the other hand, if persons believe that the particular VoIP
system that they're using provides better security than POTS,
they're very likely to be much more open in their communications
over that phone system. If it turns out that the supposedly "secure"
system really isn't secure, they've gone from the frying pan into
the fire, since the care they had been using in their conversations
in the analog case is likely to have been abandoned.
