To be fair, some days just aren't your day. Lots of folks break themselves on the good ole fashioned squat too

etc....
I's not the fault of Squats that injuries happen. The examples you cite, are competition power lifters. When you take a perfectly good exercise, such as the good ole ATG Squat, and turn it into a weight lifting competition, then of course you'll get injuries, as in any sport.
For general strength training, and bodybuilding, squats are excellent. Getting up to within 20% +/- of your body weight, will facilitate natural GH release, and incremental increases of weight on each training session, will work wonders with 20 rep ATG squats. With plenty of fat and protein right after exercise.
