Evil is a road paved with good intentions, or it goes something like that.

There's no nothing wrong with starting a dialogue with "hey! this thing you are doing is wrong!" and I will continue to do so. I try not to judge too harshly on just that though. I hold back the anger in reserve to see how they react once it starts coming to light. Covering up the existence of potential wrongdoing, keep in mind the courts could likely say the tactic is legal, does not bode well for appearances.
