I don't think so. I am not saying you can't criticize the game. What i am saying is that you have no right to tell him what to do with HIS GAME. Even if you are a SUPPORTER. (definition definition definition)You missed the whole point then.
It's like telling to people how to live their lives. You are not happy with the current situation fine you can say it once or twice if it doesn't change move on go look for something else. And that would be the right thing to do.
But instead of that you come here everyday crying all day long and shitting the bed so no one can enjoy being here anymore...
