I guess it would all depend on what the divers were told in advance, whether there were other boats around who could be asked to go get them, whether they would be in danger simply floating at the surface while waiting for a pickup, etc. That is why I like the Reef Divers model of briefing divers about this type of situation and their underwater speaker system. They tell everybody before their first day of diving that if there is an emergency, they may be left at the site while taking somebody to shore in an emergency. They use their underwater speaker system to alert the divers to get away from the boat before they start it, and you are told to do your safety stop, then surface and gather around the mooring ball to wait for pickup. This works because they generally have multiple boats out at any given time, and they have a relatively short trip to the dock and can come back soon even if there are no other boats available. Having the mooring ball to gather around helps keep people from drifting off and getting lost.Although it has been many years since I have done so, I used to peruse the annual DAN reports carefully and provide analysis on ScubaBoard, usually because people were so frequently misstating them.
It is extremely rare for a dive operation to be considered at fault in a dive fatality.The largest portion of dive fatalities are the result of health emergencies, principally cardiac related. Obesity has been associated with a large percentage of fatalities.
The rare cases for which an operation can be blamed can include things providing improper rental gear, a dive guide leading divers to inappropriate places and depths, a dive guide losing track of a diver who goes missing, bad gas (carbon monoxide), etc. These things happen, but not often at all.
It is very common in Scuba for people to assert that even those cases do not count, since a dive operation has no responsibility for your safety and your decisions during a dive. That is pretty much not true. In those threads, dive operation managers or owners sometimes step in and say that they absolutely expect their employees to be responsible for the divers. A few years ago a Florida operation was severely punished when they failed to perform an effective rescue of a diver struggling on the surface. A San Diego operator went out of business when its on-the-boat DM jumped into the water to help a struggling diver, and his wrong-headed efforts led to a drowning. These uncommon events usually make big news.
I am sure in a more remote drift diving scenario that might not work quite as well, particularly if there were currents or waves taking them towards dangerous conditions and no other boats nearby available to pick them up. If not, all of the divers have a floatation device strapped to their back and shouldn't be in imminent danger just floating at the surface for a while.
