I'm not going to be mad that they are trying to enforce a law. Is it the most useful thing they could be doing? Probably not. Are there other laws being broken in their immediate vicinity they could be addressing? Yes. Are they showing preferential treatment to a particular group of people? .... okay, I'm not mad, but at least a little irritated. Maybe more disappointed than anything.

Just because the trucks are wrong doesn't mean the cyclist wasn't wrong too. I feel that going with the pedestrian signal, unless you want to walk your bike, creates a hazard for pedestrians. And just like cars, you don't get to decide on a red to just drive through because nobody's walking your way.
