Originally, there were three rationales used for extra charges for Touch-Tone
(btw, it's no longer a trademark; after the divestiture, AT&T wanted to keep
it for the equipment, and the BOCs wanted it for the service, so it was just
thrown wide open):  (a) to recover the direct costs and development costs;
(b) to discourage everyone from switching immediately, thus creating a heavy
demand for new phone sets when the old (leased) sets were still perfectly good;
and (c) (the kicker) as part of the explicit policy of subsidizing basic
service, the regulatory agencies decided to charge for *value received*.
Thus, since people did like Touch-Tone better, it was rational to charge
for it.

P.S.  This is entirely unofficial; nothing I'm saying is in any way the
policy of AT&T, etc.
