I can't see any case in which the advertising clause restricts a
modification of the program. Can you? (Note that it is a *part of
the license*, not a part of the program.)

The advertising clause does not say that you may not remove a block of
text, except in the incidental clause that the words of the clause are
part of the copyright statement. And indeed, we have in the past said
that requirements that are there only to preserve an attribution of
credit are not problematic.
