Pro pool players are not elected officials. Just because they represent our sport to the world, we do not get a say in how they behave.
Now, if they break rules (unsportsmanlike conduct, sharking, etc.) then their opponent may ask the ref to take action.
If, on the other hand, they decide to approach the game in a way you disagree with, there is really no recourse available.
You may as well get mad at Efren for not getting upset when he misses. Tell him that he needs to take the game more seriously. It is clear that he does, but he doesn't see the need to reprimand himself for a mistake made.
It is a free country, and if you wish to compete day and night for 10 years, and find yourself fortunate to make the finals of a major, I will give you permission to play however you would like.
