Yes - agreed. Most of what I've seen has been toolbar-only effects, especially for high visibility businesses and brands.
But I feel for the medium PR site who is even suspected of being in the link marketing business. Nothing I've seen can be 100% proven to be cause and effect, but it sure does look like ranking troubles can come from suspected link marketing.
