To say that dive ops are "actively promoting" the idea that divers should place their safety in the hands of their DM and pay the higher price because they are unable to dive safely without such guidance is again, simply ridiculous. I haven't seen that "promotion" anywhere, all I see in most places is that either a dive guide is included in the cost of the dive, or it's not, then the cost of hiring a guide is $XX as listed on their pricing page, with a few encouraging things thrown in to promote their DM service such as they will take care of navigation and they can point out more critters, that sort of thing.
It is certainly better for the dive community (both sellers of services and divers themselves) if divers are self reliant and there are less accidents and less lawsuits and less bad press.
Once again you start to make a valid argument, which subsequently implodes because you are doing a poor job of presenting it. What is all this nonsense about "if they weren't happy to make the dive together they never should have got in the water?".
Divers usually experience problems AFTER they splash in, and find themselves in an unexpected current, or deeper than expected, or colder, or they have an equipment issue, or they see a really big fish, or any number of issues that only arise during the dive- at which point the divers are supposedly trained to know enough to call the dive, and if they persist on continuing the dive as the problems continue to intensify, they have only themselves to blame.
