Running a server program on a publicly accessible machine is not
the same as (re)distributing that program.

Anyway the FSF states that, in such particular situation, "it would be
legitimate to require release of the source code" (if the program is
GPL'd, of course). See


But, AFAICR, the GPLv2 text doesn't say that such case would be
equivalent to (re)distribution.

Quoting from the very text of the GNU GPL
(http://www.fsf.org/licenses/gpl.txt, section 0.)

: Activities other than copying, distribution and modification are not
: covered by this License; they are outside its scope.  The act of
: running the Program is not restricted

That means you don't have to accept the GNU GPL in order to /use/ a
GPL'd program.

Correct me if I'm wrong.
