I agree it's a tragedy when any diver is lost, and I mean no disrespect to the family, friends, or Mr. Jones who acted heroically to try and rescue/revive the victim. My deepest condolences go out to all of them.
As for the analysis of any accident I feel that more should be done to learn lessons and apply them. Of course the physical cause of death will be drowning, it seems shortsighted to focus on the coroner's findings. This was a trained diver with all the acroutements, training, and I assume experience required to participate and exist under the water, drowning simply implies that something in the training and equipment went askew and allowed water to enter the airway. Newsflash, that's what happens when something goes wrong. Looking deeper to identify what went wrong should be the objective in these "investigations."
