What would you do if this were your daughter?

My daughter is 8 years old and has been taking dance classes since she was 3. She goes to the same dance studio that me and my mother went to as children. The studio is one of the best in our state and the owner is known for being very "tough". Starting at 8 years old it is now a requirement to start Cecchetti. This is a strict type of ballet.. the girls learn movements of dance in French and are required to take an exam (physical and verbal) at the end of every grade. The class goes up to grade 5. The teacher of the class is the same woman that taught me as a girl. She is 90 years old now.. no joke. To be quite honest, the way she teaches can be verbally and emotionally abusive, in my opinion. I remember her making girls cry (including me) all the time when I was in her class and always talking down about the "heavier girls" especially. She basically called them fat and told them to suck in their stomachs. I'm very slender but, I was still talked to horribly many times. Whenever I tried to talk to my mother about this, I was dismissed and never felt like I had a choice in going to dance. When my daughter had to start cecchetti this year, I thought maybe the woman had changed by now. Turns out, she has not. She recently told my daughter that she should just quit dance because she will never be good enough. I was furious. I remember being young and seeing the moms coming in to complain about this teacher and they made them look crazy. They are always saying that it's "constructive criticism" and that it's tough love. I told my daughter that she can absolutely quit dancing if she wants to and that she can do anything else! I do not want her to feel like she has no choice like I did. Lately she has been waffling back and fourth. Whenever the day comes for this certain class, she literally cries that she doesn't want to go. It is now a requirement so she will have to take it if she wants to continue dance here. I think I already know the answer to my question here but, I'm just curious what you ladies would do? Do I allow her to make her own decisions here? The dance world is vicious 😪😤 Do I take this as a way of showing my daughter to ignore what people say and believe in yourself (prove them wrong)? Or do I forget the positives of this studio and say I'm not allowing my daughter to be talked to this way?
