I agree that that is a public performance of the software, but teh GPL
allows that: once I again point out the clause in Section 0:
"The act of running the Program is not restricted, and the output from
the Program is covered only if its contents constitute a work based on
the Program (independent of having been made by running the Program)."
So in the vast majority of cases (unless the output constitues a "work
based on the Program"), you can place GPLed software on a Web server and
allow others to run that software.
Now, the FSF may regard this as a mistake on their part in including
these clauses in the GPL V2, but copyright holders who have licensed
their code under the GPL may not share that view. In fact, they may be
very pleased if their software is actually being used by third parties
through a Web server.
