Its not really "bullshit". Stupid as the law may be, it is a law, and breaking it means that you are risking to have to pay the consequences for it, which are minor in this case. Just because someone else does the same thing and does not get in trouble does not take away from the fact that you did.
Just because someone else doesn't get caught stealing is not an excuse for you to not be punished for stealing. I'm not suggesting you are stealing or anything, its just an analogy. I understand your frustration, but just look at the simple action <=> reaction: You posted it "illegally" and were caught. Don't let yourself become angry over what someone else may or may not be getting in trouble for. The only thing that matters is that you did, and all you have to do is delete a video and move on, its no reason to get worked up over.
