No such thing as a bad exercise - only bad application and instruction.
As Obi-Wan wisely said, Only Sith deal in absolutes.
This is a coaching problem. You don’t know what you don’t know. I’m not even a squat absolutist but guys with long femurs and short torsos can squat just fine with an adjustment of mechanics. A more horizontal back angle is not “wrong” so long as the barbell stays centered over midfoot. I’m a long femur short torso guy myself. Here is a perfectly fine paused high bar squat.
