The comms. on Sharapova match also said the grunting must be stopped especially if it is appearing in the men's game. I thought the grunting was too much. They all give a little grunt now and again but I have never heard any male player make such a dreadful noise.
The thing is, I think they are approaching the grunting issue all wrong. What they are trying to do is eradicate the grunting from the juniors, or, to put it another way, using a bottom up approach. However, to my mind, if they dealt with it at the top, Sharapova (being the worst to come to mind), Williams, etc, that would feed down to the youngsters and get rid of it from the sport quicker. I know there is an argument that someone who has grunted for years, like Sharapova (does she grunt? I'd say she is more of a screamer) for example, wouldn't be able to stop now, but surely being punished for it, a warning and then a point penalty say, would concentrate the mind.
The thing is, a lot of players grunt. Andy has been known to, in fact if you close your eyes and listen to him playing it is hard to know if you are hearing him or Ferrer, because they grunt the same way. However, the key, it seems to me, is if a player is hindering an opponent, or spoiling a match for those watching. If you watched Berlocq against Andy there were several times when he was still grunting as Andy was striking the ball. That has to be hindrance however way you look at it, and as such Andy was right to complain.
