a) It does seek to make money
b) People find it very annoying
c) You can never know whether there isn't a dying man behind the wall
you're leaning against while talking sotto voce.

There is no guarantee for this. RF levels inside a modern steel/concrete
building full of pipes and wires can jump as much as 55 dB from spot to
spot. If a fade-out occurs at your end while walking around and talking
the cellular's Tx power goes full tilt at the same moment or within a very
short time. I can feel mine go 'cold warm' against my ear when this
happens to me.

I aggree fully. However, people who are on the listen all the time and go
to such places, purchase pocket vibrators which make the problem less bad,
and tend to walk outside to talk.
It would not be usch a bad idea to make a vibrator mandatory in every
cellular phone sold imho. The small extra price would not be an
I also think that some extension to the cellular services to include the
enforcement of 'no talk' zones marked by local small code beacons or such
in hospitals etc would be a good idea. In this way, it would be possible
to even equip medical and other systems with a 'no cellular' beacon so it
turns any nearby phone off the air by itself. Some coding &
cryptographical issues arise but I think that they can be overcome with
currently legal means. Maybe the current text messaging system can be
adapted for this (to send a crypted message to turn callout / answer
service off for a certain short amount of time).
