As the article mentions, when you try to do as many reps of say an Olympic lift in a certain amount of time - like the squat, it's very easy to undermine proper form, which is what leads to injuries in CrossFit. Since Crossfit is gaining popularity, a lot of these types of lifts are introduced and learned within a Crossfit gym, so there's little time to be acquainted with the proper way to do the lift. Thus, when someone leaves/quits the gym, they're not leaving with much of value: the strength they gain isn't specific to any one sport (unless that sport is, "CrossFit" which is also a headscratcher), and the exercises they've learned could have been done for years improperly. That's another recipe for injury. That's a lot of strange minuses for a gym that's very expensive to belong to. My comment was a joke, but the problem with injuries due to improper form while lifting is very real. It's not specific to CrossFit, but as I've mentioned, the focus on # reps in a specific amount of time can exasperates that problem. I myself have no investment in any commercial competitors of CrossFit. I'm a very fit person, but not in any way to CrossFit would measure. What I see personally in a CrossFit physique is a lot of muscle and weight that doesn't do a lot of good in the areas of sport that I practice: running, cycling, and climbing - all of which benefit from a strength to weight ratio that would not be attainable utilizing a CrossFit regime. CrossFit ideas have been attempted to be shoehorned into these things (CrossFit Endurance), but it's seemed as somewhat of a joke, if you're anything close to an elite athlete.
