Not all tubeless rims have the inner safety beads. The third pic is a Morris wheel that, ironically, I was told could not be run tubeless.
Was the Morris wheel an aftermarket one or one that came with a production bike? (Intended use for racing, perhaps.) Not much liability risk for the maker there, if so.
Certainly there is good engineering and bad engineering. And also sales and marketing types who think they are engineers and rely on labeling to sell product.
I've tested many devices that claimed compliance to a standard, but didn't.
For the first picture you posted, I'd claim that the wheel didn't really qualify for a street driven tubeless spec wheel. If the maker claimed the wheel was approved for use on the street, and an accident occurred, they would be liable for a pretty easy to win lawsuit claim. If they are still in business today, they wouldn't be, after the jury awarded damages, I'll bet.
If it was a tire shop that told you they could not be run tubeless, they are right not to assume the liability, as it is not built to tubeless rim specifications.
However, if you are interjecting that "buyer beware". I'll go with you on that, easily.
Certainly, if you buy "race purpose" parts and use them on the street, then you assume liability for their proper function.
Cheers,
