Again you don't seem the distinguish these concepts:
1) Apple doesn't want the device used for tec diving, they are appealing to rec divers. They discourage >40m because they don't want safety issues
2) The watch sensor API is capable of giving readings below 40m, no documentation says otherwise
3) The watch itself is rated for 100m depth, this is separate from them discouraging diving below 40m
4) The demo app (and possibly oceanic app) locks you out at >40m but so far we have no indication that thats enforced by the watch OS or API.
I have to say, it really feels like you're trying not to understand these points and are just dead set on hating on the device. I don't feel like you're communicating in good faith when you purposefully seem to ignore some of these critical points.
