I can see someone strapping the helmet to their head, then get a leak while 1m deep. They notice when it fills up. Panic and try to get it off, can’t. Surface, it’s still full of water because the leak is at the air entry hole and they designed it to fit snugly around the neck and it won’t drain without tipping upside down. Drowns while struggling to undo the straps holding it on
I’m assuming you didn’t watch the video, but this particular helmet design has a completely open bottom. the only thing keeping the water beneath you out is the positive pressure from the air hose. Any excess air flows out the bottom.
it needs weights attached to it to keep it from floating (he attached just enough weight to keep it neutrally buoyant). If it sprung a leak, you would easily be able to remove the helmet either by lifting it up off you, or tilting forward or to the side and sliding it off. it is not strapped to the person at all.
Hm. Out of curiosity, do also believe that instructional videos of how to do house construction, electrical work, or brake repair on cars should not be freely available to prevent people from watching it and doing incorrectly and dangerously?
Your previous comment lead me to think that you disapprove of instructional videos of things that if replicated by someone who does it incorrectly it would become dangerous or life-threatening.
I’m not super well versed with diving, but wouldn’t the excess pressure and air just go out the bottom of the helmet? it’s open to the water below, similar to shallow-water helmets, which are used by untrained tourists.
Should be ok as it isn’t going that deep anyway. If it fails you get out and surface.
Oh I know, and I’m not worried about the guy trying this in his pool
I’m worried about the idiot who thinks this too will work for a 30 meter dive, because there is always THAT guy who knows it all

Yes, this one does. Someone copying it may make poor choices and change it in ways that are dangerous.

Also believe? I don’t think I ever said anything shouldn’t be freely available.

More speculation on how someone could mess up trying to copy it if they don’t consider safety
This too
Way too many ways for this to go wrong in the hands of dumb people
Iron lung diving snorkel setup. Allows you to overcome the pressure and use a 15m long snorkel!
And you accidentally set it to the wrong depth and blow up your lungs.
How would it blow up your lungs?
Overpressure, 10m deep is roughly double the pressure at sea level.
