What's the reason for the backlash against SL?

I'm currently following SL, but only started taking it more seriously in July this year. Never really lifted before this.

175cm
68KG

All 5x5 except DL which is 3x5
Squats 80KG
Deadlift 100KG
Bench press 60KG
Overhead Press 37.5KG
Pendlay Row 70KG

I started OH press later which is why I guess it's low. BP is low too because I injured my shoulders and elbows for some period.

But I'm not satisfied with my squats. Feels like I'm plateauing already or maybe my form isn't good.

Anyway back to the original question - why the negativity towards SL?
