Thoughts on toddlers on 'leashes'?

Hahaa had to come back and say that I experienced some leash judgement at the farmers market today! Some woman rounded the corner & say my daughter and said, “Oh God!” and rolled her eyes at me! It’s funny how controversial an item it is. I mean, I see toddlers drinking soda & would never think to roll my eyes at the mom. We all do the best we can and what we think is best…why does the leash get such a reaction while a mom nearby had her daughter strapped into a stroller playing with an Iphone?
