Very few, in my experience.  About the only real abuse of fuzzy
control that I know of is the tendency, especially in Japan, to put
a tiny useless chunk of fuzzy logic in a consumer product, then slap
the "fuzzy" label on it.  In Japan, the presence of fuzzy logic in
a product is actually a fairly strong draw for customers.

I'm afraid that I hear this kind of comment from a lot of 
"professionals" in the field who really have *no idea* what fuzzy
control is all about.  It comes more from pure conservatism, and
from the rather old-fashioned aversion to nonlinear systems in
general, in my opinion.
