It's just that things like this seem to be very selectively enforced, and when you have a bunch of rules that are only enforced when people feel like it, it's using the rules as a weapon to do exactly what the rules are supposed to prevent. It doesn't really matter if Dave in particular is there or not, but if not him then I can name a LOT of musicians, actors, athletes and other entertainers that also have no business being on Wikipedia.
Anyhow, whatever. Does anyone actually use Wikipedia as a real source for information? It's OK to get an overview and maybe point you in the right direction, but it's not a very good "source", IMHO.
