The real trouble with the advertising clause is that it breaks compatibility with several other common licenses. Some of the BSD advocates actually like this because it causes trouble for people who use GPL code (the usual holy war justifications), but the net result is still that you have two otherwise-useful pieces of code that become mutually incompatible for political reasons.
