CITA has a bunch of requirements that it requires its members to adhere to: Safe Diving Standards | Cayman Diving, Dive Caribbean | Dive Cayman
There may be requirements in the insurance policies that the dive companies are required to carry as part of their membership of the CITA.
And then there are the things that dive operators choose to make their standards.
CITA has a bunch of requirements
and recommendations. A lot of things are recommendations, if they're mentioned at all.
If something is against the dive ops chosen policies, or maybe their insurance, that's what they should say.
Whether or not it is law is rather immaterial to me - some dive ops might claim it is in order to try to put off someone who is doing their best to go against the Dive OP's chosen policies. It may be bending the truth, but if it deals with someone that is being a bit obnoxious then maybe it's worth bending the truth a little. If a dive op isn't wanting to work with you under a certain specific set of conditions, then it really doesn't matter why.
Perhaps immaterial to you, but not everyone. To me part of this is about the principal of the thing.
Besides the practical example Rich mentions, most people simply dislike being told something that's not true, even if it doesn't impact them directly. Maybe the root cause is that Cayman gets too many casual divers they're afraid to set loose and it's just easier to "bend the truth", maybe it's because it's inherently conservative. But that is little comfort to the people it affects without good reason, or people that want to come there and would like real information, or people that are simply partial to honesty. There's got to be a better way to handle this than lying. Anyone remember the Bob Soto "Gold Card?"
Either way - when you visit a country and ignore the way things are done and insist that things are done your way is the ultimate arrogance, in my book.
I don't see ignoring or insisting or arrogance, as much as confusion created by ops "bending the truth" however suits them, and unhappiness about policies that don't make sense in their time. I can't think of anyplace that hangs their hat on the rules and regulations excuse so much
where it's not actually true. Sure other places have restrictions, some more restrictive than Cayman. But they're generally actual restrictions, not ops passing the buck for their choices.
But to come back to the broad subject of this topic - with the exception of solo diving and the laws I outlined above, then the Cayman Islands are as restrictive as most other dive destinations. It's quite possible that there are some divers on the fringes who want to go outside those - they need to find somewhere else to go, but for the rest, the place feels safe and free to dive.
Things that people have complained about in the past may not be issues anymore, at least not very often. But while old restrictions (depth/time/computers/nitrox/guided diving/whatever) may have faded, the _pattern_ remains. Solo diving is just a current example. It's become acceptable in some other places, especially if someone is appropriately certified/equipped. In Cayman, "against the law/regulations" tends to get thrown out as the reason, never mind that there seems to be an op on Brac at least that is ok with it. And no actual law or regulation that anyone can cite. (The CITA doc doesn't mention the word solo, and mentions buddies only with regards to unsupervised wall boat dives - and that one is fuzzy as to whether it is a requirement or recommendation. There's lots of mention of "discretion of the dive op.")
