I don't think it's missing the point, but you do want to be aware of the context a little bit. Randomized controlled trials are often held up as the gold standard of evidence, and they are good when it is possible to carry them out, but the point of the linked study is that the kinds of treatments it is possible and ethical to perform RCTs for limit their applicability. In this case, it would be unethical and criminal to get volunteers to jump off airplanes at 10,000ft with placebo parachutes, and the kind of RCT it is possible to carry out (this study) does not show parachutes to be effective. Thus no RCT showing that parachutes are effective is possible.
