Not a qualified climber, but as someone who has fabricated a lot of parts for race cars/motorcycles where the dangers can also be great I can tell you that this is a glaringly apparent flaw in design. Would cost them so little to recall them and simply replace the third catch piece with one made from a thicker material.....of course that would require admitting they have a problem. I hate to speculate, but I wonder if there has been a backroom sealed meeting where costs of action vs inaction have dictated the wrong path.
