I think the current generation has absorbed so much cynicism that a concept like a legally enforceable honest service just seems like a joke. It's a blanket assumption that everyone is out for themselves so why punish anyone for it. I've never personally observed or even suspected a kickback from having been paid, but vendor selection and contract enforcement is so arbitrary I'm not sure any corruption would have made much difference.
I've been on the receiving end of attempted bribery and other attempts at pressuring a couple of times and I made sure the party attempting that would never ever do it again. Daylight really is a pretty good desinfectant.
