I do feel that irrespective of the perceived/real transgression a cyclist may make I don't think just because a fellow cyclist is nearby/passing that gives them the right to speak to another cyclist other than of course a pleasantry as often happens (not in London though). Just because I ride a bike for example I don't want other cyclists to think they can lecture me about something they think I've done. If I've done something I shouldn't have or have made a mistake I'll know already.
Car drivers might hoot and shout obscenities at each other but it's more road rage from them towards each other rather than lecturing and they do it in the hope they can speed off which they mostly do. They're not encouraging a dialogue they're just being aggressive and probably expect an aggressive gesture in return.
I just think you're entering a situation which can just escalate as the cyclist being shouted at isn't going to appreciate the lecture and it is unlikely to change their behaviour (much).
After all as a pedestrian would you lecture another pedestrian who didn't wait for the "green man" for instance at a crossing - no probably not.
