> Not the only one, but the notion that the only way to build muscle is to 'tear up' your muscles with huge lifts is both outdated and wrong.

I think you're misunderstanding my point. The bodyweight squat is ineffective because you cannot change the stimulus; the only training variable you can adjust is the number of squats you do. Because it's a relatively easy exercise, this quickly means that you cannot subject yourself to sufficient stress with it, both for myofibrillar and sarcoplasmic hypertrophy purposes. Nobody in the history of the universe has ever gotten big and strong on bodyweight squats. It has never happened and it never will happen.
