1min high-intensity exercise 3x a week improves fitness as much as 3x aerobics

This is a criticism of cross-fit specifically and not HIIT workouts in general. I'd personally not recommend this training to newcomers but that's because I think the study is total bunk, not because I'd be worried about an injury.

Crossfit is bad for most people for other reasons as well. For example, look at how they do pull-ups [1], it's basically a fitness meme at this point - they use form that doesn't encourage general strength, just swinging around and putting pressure on the arm/shoulder joints on the way down for the sake of increasing competition rep numbers. This seems utterly pointless unless you really care about winning Crossfit competitions [2].

I feel like there is Crossfit the brand and crossfit the idea of group fitness helping people be accountable, learn proper form, etc... The former is garbage, while the later can be good.

No, "most people" wont do that kind of pullups in crossfit. Yes, those doing competitions are optimizing for something else (reps) than general strength. But most of those doing crossfit actually focus on the general strength.
