I happen to like the fact that they are pinked. If I worried about my machines getting fuzz in them I would never be sewing. Look at what happens when you sew with flannel, or fleece. Fuzz everywhere. I get my machines cleaned and serviced at least once a year and defuzz them regularly, so the pinking fuzz is not a problem for me. Let's face it, sewing is a very "fuzzy" hobby.
