I think the original mail from Bruce was about the old one in the 1.0

This page also talks about the old deprecated BSD version of the clause.

The old version of the original BSD license and the old 1.0 Apache
License really were obnoxious because they demanded that "All
advertising materials mentioning features or use of this software"
should add specific comments about some of the authors. Not just in the
software and/or the documentation distributed together with the
product/derived work.

I agree. But maybe we need a new term to distinquish the old obnoxious
version of this 'advertising clause' and this new 'acknowledgement
clause' which seems very reasonable.
