It is true that is why knee injuries occur from squatting. Your ligaments in the knees are not strong enough to support heavy weight. If your knees extend past your toes your squatting incorrectly. That tells me your weight is sitting on your toes and not your heels and outside of feet like it should be. If you doubt this continue squatting that way and as you age your knees wont be worth a damn. I urge you to do research on the best squatters in the world. Watch their form, none of them let the knees extend past the toes.

I don't think so. The position of your knees at the bottom of a squat is related to your anatomy and the length of your bones. Longer Tibia/fibula will extend your knee out farther naturally. Longer femur moves your center of gravity back. Your center of gravity has to be over your feet, or you fall over. Your balanced position depends on your body dimensions. If you unaturally try to move your knees back from your natural bottom position, the weight has to move forward to stay balanced. To do that, your upper body has to be more bent over (more horizontal), putting more strain on the low back and hips.
Here's a study that supports what I'm saying. Note that knee torque is slightly less when forward motion is restricted (30-40% less just eyeballing the numbers), but back and hip torque increase over 1000%.
