The NSCA did a pretty poor job of retracting the paper. It was still available online for quite a long time after its retraction without any explanation of the reason for retraction.
Read a few posts down to the article in the Montreal Gazette: "“Are CrossFit Enthusiasts More Prone to Injury?”. The Devore paper was cited in that article published June 11th, so damage is still being done.
I'm not in a position to know if the paper ever impacted anyone's box. But falsifying data in a scientific study to attack a rival corporation should not go unpunished. Scientists have a duty to pursue the truth and must be held accountable when they don't.
CrossFit has been extremely transparent about this battle with the NSCA. If you read some of the info CrossFit has posted about the case, I think you will be quite surprised about what happened. Injury data mysteriously appeared in the third round of the peer review process. And big name exercise scientists seemed to be behind it.
If CrossFit didn't fight vigorously to defend its reputation, it WOULD have an impact on everyone's boxes.

Tom,
.Along with ACSM, ACE, and others, NSCA lobbied for laws that would have made CrossFit's affiliate model illegal (through occupational licensure). NSCA needed injury data to justify licensure. They concocted it.

As Tyler mentioned, NSCA's fake study was cited and covered extensively in the media. Academia continues to cite it, despite the 2017 retraction. And it is the single most-viewed article the NSCA's journal has ever published. Outside Magazine advertised it on the front page via the headline "Is CrossFit Destroying the World?" 

Had CrossFit let this fraud go, as you recommend, the NSCA would have continued lying about CrossFit and convincing the world that CrossFit is dangerous, in support of their nefarious lobbying campaign. 

I'd ask you if you think it matters to CrossFit affiliates to be free from anti-competitive legislation and not have their reputations smeared by injury myths, but I won't insult your intelligence. Of course it matters to them. 

It is true, boxes may not realize that prospective members are concerned about injuries due to a decade-long campaign of false and baseless claims, orchestrated by CrossFit's competitors. It is not their job to understand these details, though. It's their job to improve their members' lives. It's CrossFit HQ's job to make sure no outside entity gets in the way of them doing that. That's what we are doing in the NSCA lawsuit. And it's an honor.
