I'm not sure about what you mean with celebrity refs? Are you saying they are making decisions to be noticed?
I think we have to understand refereeing a game is extremely difficult, at any level. As the human mind only has the capacity to pay attention to a number of elements at one time, it's almost impossible to referee everything at one time. This means referees will have a pattern to what they are able to pay attention to and therefore be able to referee.
As this is a contact sport and bodies can be unpredictable in contact, it will be almost impossible to referee exactly the same as one another in the time they have to make decisions. Barnes today was calling penalty for not rolling away, even when the player had let the ball go, the player could not move and the ball was playable.
All we can ask is that they are consistent in what they do. They need to be able to explain their decisions to the players and to refereeing peers. After the game you'd hope Poite would be asked why he refereed the breakdown as he did.
