I did not intend any fun, nor criticism.

Yes, but thats *not* what the ZPL clause 4 says.

ZPL says you only need to include the acknowledgement in an
advertisement "mentioning features derived from or use of
this software".

As I read this you need not include the acknowlegement if
your advertisement:
a. does not mention features derived from Zope
b. does not mention that it uses Zope
